Icons for files opened with a given app disappeared

[GLCH]

I have installed Catalina 10.15.7 and for some reason the icons for the ".tex" files to be opened with the app "TexMaker" disappeared. Namely what I see for a given file is a generic icon like this: https://i.stack.imgur.com/fRz5m.png

On the other hand, when I open /Applications/texmaker.app/Contents/Resources, the `texmaker.icns` is: TexMaker.icns

When I have a file ".bib" or ".sty", the icons are correctly displayed. These formats are given in the `.plist` of the TexMaker app copied below. I do not understand why the same does not happen with ".tex" whence the question:

How do I get the correct icons for the ".tex" files?

I tried to delete some cache files, kill the Finder, turn off/on my computer, go to safe mode, ... nothing seems to work!

.tex-files are still associated with TeXMaker as default program to open with? Does location of a .tex-file effect this, e.g. icon on external drive is „correct“, on the Finder desktop they show generic ones?

I connected an external drive and apparently now the icons are back... (I did not change anything). That's strange but nice to see.

By any chance a newer version of TeXMaker is located on that external drive?
