Hi, I really need some help. I was rearranging file locations and trying to clear up some space and somehow broke the ability for Unity to operate on my laptop. The pictures of the errors and what’s happening are below.
Steps I’ve taken:
- I’ve restarted my computer several times
- I’ve completely uninstalled all editor versions and the unity hub (twice), including deleting all local app data for unity, emptying the temp bin, and clearing the keys in the registry.
- I’ve started completely new projects, checked old ones that used to work, downloaded sample ones from unity learn just to make doubly sure that it’s not me being dumb.
My current theory is that this has to do with me clearing some data from a National Instruments folder. I’m new to programming and just read online that this is needed for .NET communication, but would this be why Unity keeps failing then?
This has all taken more than a few hours and I’m drawing up a complete blank on how to fix this if anyone has any suggestions, please. I’d really appreciate any insight.
Update: I’m able to make new scripts, objects, scenes, etc. but I can’t attach any script components to game objects because “the script class can’t be found”
Update #2: Checking the Editor logs shows that the Tundra build is failing, and the “93 items updated” matches the 93 errors that are shown. No idea what Tundra is, but that’s something to look at now!
Update #3: I’ve now additionally uninstalled some Windows updates and reinstalled them so the framework is running properly, but I did also download the .NET 5 on my own. The issue is still persisting
