Grey patch on screen after sequoia 15.7.3 upgrade for Macbook Pro 2018

I have a macbook pro 2018 model. It was on Sequoia 15.7.2 until yesterday and everything was working fine.

I got an upgrade notification yesterday and I chose to upgrade to Sequoia 15.7.3. However, since the upgrade

I am getting a grey patch on my screen right in the middle. The patch is about 2 inch wide and spans top to bottom of the screen.

Quick search on google, I see some people mentioning 15.7.3 upgrade came with some non-compatible Tahoe 26.2 updates. I also remember some mention of Tahoe in the upgrade information box when I chose to upgrade.

I tried restarting, changing the resolution etc, but it just doesn't go. Anyone facing same issue or know how to fix this?
