Hi, got a weird problem where clicking on material shader selection dropdown triggers “Hold on - InspectorWindow.MouseDown” for 12-15+ seconds and it happens every time the dropdown is clicked even after I click asap it finishes the previous hold on. I’m using Unity 2020.2.4f1 URP and I’ve experienced the same issue with previous 2020 versions since the whole “hold on/ busy for” stuff was introduced.
not like my project is super huge, just working on mobile game not that many shaders too.
to see what might be causing the issue I tried deleting all custom shaders(toony colors), but no luck, tried deleting the whole project and creating material with standard shader to see if the issue goes away, but still the bug persists.closing & reopening inspector, reinstalling unity, restarting pc, checking task manager didn’t worked either.
2 ways I found to fix the issue is :
- create empty project with any 2020+ then paste the project files and issue is gone for that moment, but it does start again after sometime idk what triggers that even though I didn’t import anything.
- create empty project in 2019LTS and then paste it there and the issue seems to have gone forever.
also I was using 2019 earlier everything was going fine but this issue started showing up out of nowhere because of which I switched to 2020 which fixed it for a while but occurs more easily.
I have seen posts where people complaining about the “Hold on” where imports start frequently when clicking something or entering playmode which I too have experienced, but for me it got fixed automatically, but now I got this extraordinary new one. idk how do I even send a project for bug report as it is not linked to any specific asset or script where I can show how to reproduce it 
does anyone know how to fix this issue or just wait for new release where the whole hold on stuff is reworked?
