BS player freeze during playback

[MiGo]

I have a weird issues with BS player build 1091, in the past 2 months (just right after 21H1 Windows 10 latest updates.

During playback, audio and video are not completelly sync and after 40-50 mins playback froze. I tried every possible formats, MKV, x264, H264, x265 etc and different types of video files (xvid, bdrip, etc...), but the issue is there. Sometimes playback goes smooth, but most of the times BS player is freezing (PC works fine in that same moment). I did clean Windows 10 pro install, also i reinstall BS player, but the issue persist. My hardware is completelly fine (i5 7th gen, GTX 1660 super, 16GB RAM, m.2 nvme SSD/SATA SSD storage)

Need some help please

Had some problems too after 21H1, Internal renderer showing just a black screen and subtitles out of sync on some other rendering methods. Switched to VMR9 renderless, seems to work ok. Probably something in video rendering was changed after the update.
