I'm working on a Unity project (2020.2.1f1) on both my home PC and a workplace PC (which is 64-bit aswell and has the same Unity version). It all worked fine until today, when I tried opening my Unity project from my external SSD on my workplace PC, the opening process got stuck on "Importing... (busy for )"

What I tried so far:

* Restarting my PC
* Deleting various files in a copy of the project, such as the library or the meta files (deleting those just led to the resulting project looking awful and all script implementations missing ect)

The upm.log file states:
[INFO] Resolving dependencies using SAT solver

The editor.log has a massive bunch of code, but the last line states:
[C:/PROJECTNAME/Library/PackageCache/com.unity.ide.visualstudio@2.0.5/Editor/FileUtility.cs line 22]
(PROJECTNAME equals my project name which I dont wanna reveal here)

Anyone got an idea how I can get my project running again?
