Environment

• TeXstudio: TeXstudio 4.8.6 (git 4.8.6alpha1-1-g3c26076af)
• Qt: 5.15.15
• OS: Linux Fedora 41
• TeX distribution: texlive

Expected behavior

I have a line in a TeX-file like:
\includegraphics{PE12GA0007b_Leiterschaukel.png}

Now I want to add an optional argument to the includegraphics command. So I put the cursor between the "s" and the "{" and press "[" on my keyboard. It should print "[]" and put the cursor inbetween.

Actual behavior

Crash (SIGSEGV) when typing the "[".
There seems to be some dependency on the file or active packages, as the crash does not occcur in a clean minimum file. But consistenly in my setup, even when copying the correct line, removing the optional arg and the trying to add it back in.
