Looking into the flatpak, it’s ran using aqt, so it makes sense - also now that I read the cross-referenced post, I realized I forgot to mention the very important detail that this issue wasn’t present before… HOWEVER, until very recently it did work on the flatpak, but I don’t know until when since I stopped using that in favour of running the installer from GitHub (when another annoying bug presented itself, namely the one where MathJax wouldn’t render properly and would just show as \(\) or \[\] while editing a card)
EDIT: read next post, this part below is not necessary
But the most baffling thing is that, I tried to make a venv and download some older version of the aqt package, even all the way back to 2023 when the issue definitely wasn’t present, and in no version did Ctrl+Enter work, so at this point I don’t even know what could be causing the issue
