TeXstudio doesn't autocomplete \include{} and \includegraphics{}, but works for \ref{} and \cite{}

[lphysical]

TeXstudio: 4.8.6
Qt: 6.8.2
OS: Win11
TeX distribution: texlive

Hello, I am experiencing an issue with TeXstudio's autocomplete feature.

When I type \ref{} and \cite{}, TeXstudio correctly suggests available references and bibliography entries. However, when I try to use \include{} or \includegraphics{}, it does not suggest any available files.

Here’s what I have already checked:
✅ I have properly loaded the required packages (graphicx for \includegraphics{}).
✅ My images and included files are in the same directory as main.tex.
✅ I have reinstalled TeXlive and TeXstudio multiple times.
✅ I have tried manually triggering autocomplete using Ctrl + Space, but it still does not show file suggestions.

Is there any possible reason why \include{} and \includegraphics{} are not working with autocomplete while \ref{} and \cite{} work fine?
Any help would be greatly appreciated!

Thanks.

does it also not work when you use a complete path which does not use non-latin characters ?

Yes, I believe the non-Latin characters are not the root cause of the problem. Do you think this could be a problem with my computer itself? But what confuses me is that when I manually enter the image name, the compilation works fine.

completion and compilation are two very different mechanisms.
