[fredx30]

Type of JetBrains IDE (IntelliJ, PyCharm, etc.) and version

PyCharm 2022.3.3 (build PY-223.8836.43)

Operating System

Windows 11 10.0 (amd64)

TeXiFy IDEA version

0.7.27

Description

This most likely refers to an exception where the plugin attempts to preform some kind of operation on a file thats been deleted.
I dont know what operation or why it starts. It seems to be a background job that ocasionally gets run when the pycharm ide comes into focus after being clicked.

Thanks for reporting, I've seen this issue before but still have no idea about the cause, see #2377 . Since it's a relatively rare issue and doesn't seem to have any effects, I don't think I'll spend any more time on it.
To be sure I'm looking at the same issue, could you upload idea.log from Help > Show Log in Explorer?

If it keeps coming back, just Invalidate Caches & Restart should fix it.

No wait, the stacktrace is different, here we are actually working on PsiElements that were kept in memory and are potentially in a deleted file, as you correctly determined (thanks!). Will fix that.

I tried to cut away a bit of the idea log. It should still include the entire day with this error.
