Frustrating latency problem with Timeline panel

During playback, timeline position marker either doesn;’t move until playback stops or it jumps several random times during playback.

During playback, the time counter on the timeline panel is frozen until playback stops and then it jumps to stopping position.

Program panel showing the video works fine and time counter moves forward with video playback.

I have searched the internet for solutions to latency in the timeline panel.  Apparently others have had similar issues.  I have made the following suggested changes.

• Move media cache to external harddrive – done; also set hard drive to not power down.
• Delete cache – done
• Change resolution to 1920x1080 done
• Change memory to give a big chunk to PR: I have 32GB (31 usable) have set it to 25 GB for PR and 6 for other apps.
• Changed playback resolution in program panel to 1/2 or 1/4; no impact to timeline pointer movement or time metric – done
• Have not tried proxies yet, as that seemed confusing to manage.

This is very frustrating and makes it difficult to perform editing.  This seems to have begun within the last 3 weeks.  Need More help.

I am running windows 11 Pro, 64 bit, on an Intel Ultra 7155H chip with 3.8 Ghz.  I have 32GB memory and both internal and external hard drives are very large with a lot of space.

My prior PC, with half the memory and slower chip, never had this issue with Premiere Pro.
