(SOLVED) Failed to compile java - not a regular file

Solution:

Reboot PC and then delete

EDIT:

I've deleted the folder containing the block entity class files, then ctr + z to bring them back. For some reason it seemed to have worked but I'm still looking for a fix that will make it never happen again.

It happened again at a different file, so I need a permanent solution still

I kept doing it and it worked, I'll edit this again if it stops happening

I've tried

Restarting MCreator

Reloading Gradle project

Regenerating code and build

Re-installing MCreator

Putting the files in exclusion for Virus and Threat Protection

This keeps happening and it sometimes goes away for a couple hours, but it keeps coming back. This time it won't go away, and I'm looking for a permanent fix.

There shouldn't be anything wrong with the block, I didn't change anything and it just stopped working
