Project Manager Frame Size Stuck

Something happened over the weekend when editing where small strips appeared on the right and left of my frame. I thought I had missed it when adjusting my Scale between key points but it was not. The image frame became smaller on the right and left. So I started with ChatGPT to figure out what the issue was and in the end the frame size got smaller on both sides and is now a perminent preference in my whole Premier App. Nothing I do changes this and it has been applied to all videos I have ever edited in Premiere so it seems some setting has been changed perminantly but I cannot figure out where. 

How do I get my Project Manager frame size to fill in the screen 100% at 1920/1080/100?

Through problem solving
- all my workspace "Revert to Saved Layout" preferences are now set to this smaller window. 
- My sequesnce settings are set correctly and match the source file
- Everything is set to 16:9 as far as I can tel working with mutliple LLMs to problem solve
- If I create a New sequence from clip it opens with the same issue
- If I close out of Premier and start an old video i worked on from 9 months ago it's there
- If I try to start from scratch with Premier it opens like this
