No Video Playback on Macbook Pro 13" (2018 ver)

I've read about a dozen post with recommended solutions on this subject matter and non seem to work on mine. Just wanted to see if there is a new solution or i just need to buy FinalCut Pro and cancel my Adobe. Or get a PC.

Issues:

When i play the timeline, i can hear the audio as the timeline progresses but no video.

Solutions:

• Reinstalled  Premier (Clean install)
• Single Monitor Display
• Reset Macbook settings
• Reset Adobe settings (cleared cache)
• Changed render engine
• Tested playback on different application and video plays fine (Quicktime, VLC, Finalcut Pro)
• Tested different content (mp4 quicktime DXV)

Specs:

macOS Big Sur 11.6.1 (2018)

2.3 GHz Quad-Core Intel Core i5

16GB 2133MHz LPDDR3

Intel Iris Plus Graphics 655 1536 MB

This used to work back in 2018. i've made a grave mistake of updating the OS and Adobe.
