TV Media Player won't play certain videos when it has certain subtitles videos

[fenlig]

My TV struggles to play certain video files when subtitles are turned on. I can play them from my PC's JellyFin media player/web player, but not my TV's. The video will just pause for a minute and then play maybe 2 seconds before pausing again. Once you turn off subtitles it plays perfectly like normal.
