I have this program called VideoDownloader its a Flatphub program that
Ive used for years. Now when I launch it, it starts to open then closes. Probably an easy fix but I don’t know where to start. thanks for any attention anyone could offer.
You should provide more information about your system: Which distribution, version of the distribution & version of flatpak.
Make sure that you update everything (distribution & flatpak update) and then you can try to start the application from the terminal & post the log.
flatpak run com.github.unrud.VideoDownloader
