Problems with movie rendering- subtitles

From couple days I had problems with Jellyfin. I had it installed half year ago in my home server and because I have holidays I wanted to watch couple movies. And so... some of them didnt want to play, some of them just stoped couple times during play, finally after couple errors they didnt want to play on my tv and in webbrowser. I wanted to check what is the problem but it took me half day without success. I had free time so I made fresh install of Jellyfin LXC container in upgraded Proxmox and still had problems. I was trying to figure it out and finally I got everything working: transcoding, codecs, permissions, mounted folders etc. I tested two 4k movies / sometimes one could not play, sometimes second one. I was looking for solution with chat gpt checking logs and finally the thing that was stoping jellyfin to transcode movies was subtitles. I always have .srt files next to the movie but many videos got of course subtitles embeded in movie (and probably PGSUB format is the problem). The only way to play all 4k files is to have subtitles turned off in jellyfin options (tried every way with subtitle mode/ burn subtitles in jellyfin options).

Is there a way or some plugin to force jellyfin to stop reading subtitles from movies and to use srt subtitles when it play movie?
