after effect 2025 flickering issue

hi guys i am facing weird flickering issue on this.

the videos playback is flickering suddenly (previously working fine)

the other contents i generate in the file are ok but the imported assets are flickering.

i have tried turning on or off of this feature, but its not helping. 

my AE 2025 is up to date, the Nvidia driver is up to date as well.

please tell me what can I do? thanks!
