CoreELEC 21.1-Omega Amlogic-ne Discussion

Help!
I’m using a device with an S905W2 CPU and 4 GB RAM. After updating the system from version 21.0 to 21.1.1, I’ve been unable to play videos stored on my NAS correctly. Even 720p H264 videos stutter and stop. Downgrading to 21.0 resolved the issue. Can someone help me understand what’s causing this problem?
I am not sure weather the log file could be useful? (i am not sure whether the information in the url would be available. becasue I am a new account and cannot uploade the log file)
