Session archive not loading

I am in the process of moving all of my music stuff from linux to windows (I love to solve random issues but not when i have an idea and want to make it) and one of my projects i recently created does not want to load when opening the archive. Opening the project itself from the folder almost finishes loading the editor but then just crashes, so I hoped that archiving will work but no.
I get this error:

“Extracting session-archive failed: Archive is empty”

I tried multiple times with zipping all files and also just the ones that are used (I clicked that checkbox). I have a 22 and a 230 mb archive but neither of them will load. they give the same error.

What can be the issue?
