Unity 2020 editor is broken & exponentially slower than Unity 2019 & even more than 2018,please help

Hi,

I have recently moved my development to Unity 2020 (2020.3.26f1 currently) and have witness exponentially slower response in all editor functions.

Simple things that tool milliseconds in Unity 2019 now can take minutes or get stuck forever.

This photo below is a small sample of trying to export 3 scripts to a Unity Package, i am stuck looking at the screen forever, i dont even know if will get unstuck at some point or have to kill Unity.

This is a common issue in 2020.3 and happens in various degrees in all functions, mostly is a bar that makes you wait for few seconds for things that were always instant in 2019.

All in all 2020.3 seems totally unusable for any serious work as the workflow is constantly interrupted by those waiting times.

Is there any plan to fix those issues soon, or Unity is no longer workable ?

Thanks in advance for any help on this as has created a HUGE issue in my development.

Now reached the 10 minutes mark waiting

Please help, at least let us know if these issues are planned to be fixed

PLEASE stop making new Unity versions and features, there is no need if Unity editor is not working, and focus all teams into fixing Unity 2020.3 LTS first.

EDIT: 20 minutes later killing Unity, seems this stuck for good. Good luck with my next unity action. Now i am afraid even open Unity to work.

Also in comparison to Unity 2018, both 2019 and 2020 are much slower, but 2020 case is really breaking the whole experience completely.

I found a similar issue with a user report that was resolved, maybe now returned ?
