Hi, so today I wanted to work a little bit on my project since everything was left intact when I left it and I have re-opened it today to do some programming and make some progress however, I have encountered a compiling error which doesn’t seem to go away. I have no idea what could of caused this and I already tried to find the temp folder to fix this → error : System.IO.IOException: The file or directory is corrupted and unreadable. But apparently the temp folder doesn’t exist.

Thanks, NijoMeisteR!

From the stacktrace you provided I don’t get any relation to temp files. It rather seems to be checking some source files for UObjects and then fails due to inadequate access rights. So the first thing to do should be checking all involved files and folder have proper permissions set. If you are picking up your project after some (more) time it is probably also a good idea to start over with a clean rebuild to get rid of possibly outdated intermediate files.
