Environment

• TeXstudio: 4.8.4 (git 4.8.4)
• Qt: 6.7.2,
• OS: Windows 10
• TeX distribution: none!

Expected behavior

ignore (as the best) or opens error window.
Texstudio is aware of the TeX absense and at the start gives a corresponding window.

Actual behavior

Crashes with error window:
Command txs:///pdflatex is not defined

How to reproduce

Not sure, but suspect that it occures when I put cursor on inline formula (seems that it fails to make preview of it).
