in 2020.1b12 I run an alayze selected rules and get this:
it seems to be a generic application message box…

I get this too, including others like ‘Application.Message’, 'Application.ExecuteMenuItem, ‘AssetDatabase.Refresh’ or ‘GUIView Repaint Scene’. They are caused by holdups in tasks Unity (usually) does in the background, like Refresh the scene/inspector, complete the task you just asked it to do, check if the assets in the system files have become different to the ones Unity has, or complete all other tasks for a frame. Seems to be caused by slow hardware (I am on a rather slow laptop. I sometimes get delays of up to 5 mins on these ‘hold on’ popups, though they are not as long when my system has been on for a while and gets chugging), I am currently running 2020.1.0f1 Pro Version and have been getting these messages since even before 2018, though as Unity add more and more features, and with every release it seems to be getting worse. I believe it is something they are working on, though.

I just updated my project to 2020.1.8f1, and started getting these a lot! Never had this problem in 2018 or 2019 versions. Now I am getting the Application.Tick, Application.Message, Application.EnterPlaymode and more with almost everything I do. Importing packages, entering/exiting playmode, switching scenes… It makes Unity unusable for me

Same here. I constantly have to force quit and restart Unity. Makes me not want to use it anymore.

same here, my desktop rig had its monitor to present a failure so I’m using my laptop and its horrible, I’ve been on a Application.Tick for 9 mins now because I clicked STOP IN A MOFU EMPTY SCENE that I WANT TO TEST STUFF INTO, THAT I HAVEN’T EVEN ADDED YET.
This is some 2020 bs because when I used 2018, 17, 19 or 5.x it NEVER AND I MEAN NEVER BEHAVED LIKE THIS, now on 2020 even my desktop shows these awful messages that CUT OUT THE WORKFLOW YOU GENIUSES, even though on my desktop they show for 5 to 10 seconds at a time, not to mention that it gets WORSE the bigger the project. In fact we have chosen to keep our ongoing project in 2019 due to this.
This message suddenly appeared on version 2020.1.7.f1, I had never seen it before on the same version. This message takes 5 minutes each time, even though my PC is powerful enough and does not use even half of the resources. I have a Xeon X5650 6/12 24Gb RAM and RX480 8Gb when the project is running, 14-15Gb of RAM, 5-6GB GRAM are used, the processor is loaded by 15-20% The project is on the SSD, everything is in order with it, it has 97% health and no errors. But I continue to receive this message for 5 minutes after each exit from the play mode.
I have application.message upon opening my file, but it has been there for seven hours. What do I do to fix it?
easiest solution is probably switching to UE4, the application.tick message eventually disappeared after a minute or two for me.

Getting Application.Tick and others a lot during work, with Unity 2020.1.17f1. Was this fixed with 2020.2?
Hey all, this is very curious. I haven’t seen anything like this before. Though, it sounds like this may be more an issue with the Editor side of things rather than our package specifically? I only think that because it appears some of you only started seeing this message after updating versions of Unity.
If anyone wouldn’t mind submitting a bug that would help a lot. If this is an engine side issue that’ll help the appropriate team get visibility into the situation. And if it does turn out to be something on the Addressable side it’ll help us to have a good repro as well.
I can poll my team and see if anyone is aware of something and update if I can get any more useful info.

I’ll just go back to 2019.4 LTS. I like using HDRP in the 2020.2x version I was using but it always stalled with “Hold on…Application.Tick” for, I think, forever.
I don’t know why but in my case it is caused by a script responsible for writing data on firebase. Removing the script solved the problem.
How did you found the script responsible of that ?
Please post the steps that you took for removing it.
Thanks in advance for your replies
Using an asset named DoozyUi I’ve messed something and ended with an error in the console, trying to get back to the editor and out of the play mode got this error. The asset said it detected something that could create an infinite loop but I think it stopped this and showed the error. While trying to get out of the play I got stuck to this message
I think it ended up after 10 minutes, maybe some setting in the editor to wait 10 minutes before unity kills this message?
Ok so turned out that the error was caused by the asset not working correctly when entering play mode when Reload Domain is disabled.
There was nothing wrong with me setting it up I’ve had the Reload Domain turned off
I suspect is the same for others scripts, so if any of you have this issue turn on Reload Domain in Project Settings → Editor → Enter Play Mode Settings

Got the same problem in unity 2020.2.1f1. I left it running while eating and… this is madness! Anyway, I will try upgrading to the recent LTS later, see if this solves the problem.

Upgrading to 2020.3.1f1 didnt solve the issue. I am working on a huge project and would like to continue… 
Anyone any more ideas how to solve this? I didnt mess with reload domain, so the solution suggestion above doesnt work for me.
