Youtube videos only work with audio and no video


it’s been 3days since YouTube is not showing any videos and working only with video it was working fine then suddenly the video stops and i checked other videos then the same happened
i searched on the brave community for solutions i tried disabling hardware support and also i removed all the extensions and cleared CSS rules but nothing seems to work
the videos do work in private windows
i need help ASAP
PS: my brave version is chromium 1.18.78 and my windows is windows 10
