100% used video memory after stop recording

When I click stop recording in sequencer my video memory are full in 100% a long time and unreal engine have strong freezes and only best choice is to restart the programme(( Can I drop down used memory that used render?

I have 2080 ti videocard. Project scene I make only for cinematic that have a female face with 8k textures, sss, new groom hair system

you can check the logs to see what’s possibly causing the freezing
my guess is something you may have turned on in beta mode still
