My Unity freezed on build .shaderasset problem, cant open the project :(

i was building small test scene after tweaking canvas sliders,images etc…went to make coffee, came back sure its done. it wasn’t and it was stuck so i task manager ended process, now i cant open the project,.
i tried : deleting in temp folder the unlock file,importing assets to a new project(worked) but library made the fresh project also not load. i dunno whats wrong but and since its test scene It does bother me because i dont want this to happen later on with many maps and built dungeons etc .:slight_smile: thanks for input.

Find steps to reproduce, then don’t do that! (And report it as a bug, if appropriate). You mentioned “but library made…” Can you elaborate, which library? And use source control and/or make backups frequently.

Yes,Backups…
The folder “library” that is in corrupted project folder cannot be copied/moved to a new project.it will make the project also dont load.
p.s. “find what causes it and dont do it again” sounds like a good idea,but i highly doubt there is a anything i did wrong,. I built because of changed ui,it worked then i just changed one sprite,and tried to build again…but it didnt go well…backups yeah
