Hey @DavidTveraas!
The UE client does some things that really assist when looking at the logs that you don’t get if you copy it over without formatting. Can you go through and find any yellow or red text and snip that with a few lines before and after? You really don’t often have to worry about anything that is standard white text. 
And yellow usually allows a compile but red is a hard no most of the time.
Looking through I see a lot of “Invalid value for PACKAGE_FILE_TAG at start of file.” Usually this is caused by GIT LFS only having the pointer file instead of the actual binary. Try doing a git pull!
If that doesn’t work you can also check this thread, they had similar issues and had to pull from the “Saved” directory after deleting the offending files. Can't open CTF map, Post Tag is not valid. File might be corrupted - #13 by N_otTfue
For another thing with your errors, it looks like you have a version of Vision OS that is possibly out of date? Also did you add that to your Visual Studio installation? If you didn’t that’s a big one you could do to solve a lot of errors.
Hope this helps, get back to us!
