I just had an issue with the vscodium flatpak, been using it for two months with no issue in an online course, got to learning GUIs, import module, doesn't exist. I couldn't figure out why it wasn't there, installed three different python versions of it three different ways, still nothing. Couldn't even get vscodium to point to a different interpreter that I knew was there (yet it doesn't say it's not there, just that some things won't work). Still nothing. Three hours later, after trying everything I could think of, I realized that it was because I installed the flatpak version when it clicked that it worked in Geany and I didn't have python 3.13 in my repos, yet that was the only one I could see in vscodium.
