If I open a new file is get a fatal error (see below)

When I try to access an existing file I get similar errors saying it can't acces temp files.

I tried reinstalling, I have no other processes running, I tried deleting everything in the temp folder but nothing works. At start of the application the temp files are made, eve before i want to open a document.

Error message:
