I work on premiere pro wtih braw media since longtime. But since 3-4 days, i have this recurrent error when i read a media in source monitor. I can't work normally.... I tried to update nivdia studio driver, game ready driver. Udpate premiere pro in 14.7 14.8 14.9. I cleaned my memory cache.
This might be unrelated, but worth a shot. I see that you updated Premiere Pro to various versions: 14.7, 14.8, and 14.9, as well as your NVIDIA driver. When you updated Premiere Pro and NVIDIA, did you also update Blackmagic's braw plugin?
