As promised I looked into this and here's an interim version for linux that handles external programs like ytdl completely different and might solve the issues without needing an updated ytdl. Please be aware that this is a rather experimental release - should you have any issues with it, please let me know.
Also beware that you might need to revert any changes to your system you already did to fix the issue yourself (like the proposed workarounds).
THIS VERSION IS PERFECT!! AND VERY QUICKLY!!!!!!!!!!!!!!!!!!!!!!! ON PANEL ETC :> NICE GOOD JOB!! Pleasee do not update for next DDD
