Captions are not displayed in preview or export

So my automatic generated captions stopped displaying also in old projects without me changing any settings. I already tried reinstalling and downgrading several times but nothing seems to help, been on this problem for the last 4 hours maybe anyone has some ideas. It feels like the bug occured after changing to 25. I also tried exporting and reimporting the captions nothing helps it seem like they are still there just not displayed in the preview or the exported file.
