Hi all. Sorry not sure if this is quite the place to post support for editor crashes? The editor constantly crashes especially moving back and forth Visual Studio Code. Pls see below the top portion of the crash log. Thanks in advance for any advice!

Unity Editor by Unity Technologies [version: Unity 2020.3.18f1_a7d1c678663c]

Bump >_<

I started getting similar crashes after importing Jobs 0.11.0-preview.6 and Collections 1.0.0-pre.5 packages to the project. Getting crashes in both 2019.4.31f1 and 2020.3.21f1.

I’ve been having this for almost a year now, on pretty much all 2020.3 versions since January, infact its gone through a frenzy of it over the last hour which is why im on the forums.

Havn’t been able to trace it but sometimes i can go a day or two with nothing, then next day i load it up and constant freezing all day. Interestingly playing the game in the editor and disabling code updates during play i can have it going for hours, probably days if i wanted to, its only when the ‘tick’ operation occurs and its looking for something or compiling prior to launching player. Got new RAM, changed hard disk to no avail. I had submitted a bug report but to be fair its so random a issue and doesnt really say anything useful so havnt heard back.

I have a VPN and i notice some people have had compatibility issues with that, by disabling it i thought it solved it but it was just on one of its good days, i messed around with anti virus exceptions and nothing. For me i think its a background task as once running the game is fine, its only when not in play mode updating the code it falls over and in a non repeatable way, sometimes it doesnt even need to do anything and it crashes. Seems to work better if i enter a project and leave it 20 minutes but that makes zero sense and shouldn’t be taken as advise.

It would be good if unity could release or point out a list of software or hardware compatibility issues (i have a ryzen 3700), do’s and don’ts and/or anything that might cause editor crashes when its updating itself or compiling.

I want to add, at least for me after deleting folders BurstCache, il2cpp_cache, Il2cppBuildCache and ScriptAssemblies from Library folder it started to crash less. Maybe just a coincidence since issue is very random.

Hey guys so I upgraded my computer with much stronger CPU and GPU and it seems to be crashing way less

I have a high end PC and still experiencing these crashes on unity 2020.3.18 (and previously on 2020.1). I’ve used unity 5, unity 2017, 2018, 2019 but never seen those crashes before I updated to unity 2020.

It’s crashing when I press Play or when I recompile scripts. I saw that one unity developer said that they fixed one issue in unity 2020.3.26f1, which might be related to I’m upgrading and will report back after a few days.

@skinwalker_1 Just to add, i am on 2020.3.27f1 for last month or two and finally after a year or more i am no longer having crashes, hope your experiencing the same.

After a bit more than a week of testing, yes I haven’t seen a crash, I will keep testing though, because sometimes this crash doesn’t appear for days / weeks and some days it goes like this (Unity 2020.3.18)

That’s the issue they fixed.
