Has anyone else the problem, that all videos somehow freeze at 1 minute? I've tried both Firefox and chromium, but I just cannot get past one minute rn.

Whenever I want to watch a video, the video will play just like normal for roughly a minute (58-60s) and then just stop and load - forever. I tried Firefox and chromium - both with uBlock origin enabled and disabled. My internet speed shouldn't be the cause, since I have 400Mbit/s I cleared the cache multiple times. I restarted my PC multiple times. Ads in front of the video load just fine - who would have thought...
