Mouse Refusing to Lock to Game Window

Hey yall, I am having the most infuriating technical issue. For some reason on 11/6 my mouse just stopped being locked to minecraft, causing me to click out of the game (Video attached so you can see the problem). I have tried everything to fix this, but it still happens in full-screen and windowed. It even happens when I launch the game on my second monitor, and even when I completely disconnect a monitor.

Things I have tried: -Uninstall and reinstall -Verify and repair -Changing registry values -Uninstalled recent windows updates -Disabled all game bar widgets -Enable/disable pointer trails -Update mouse and keyboard drivers and software -Tried a third party mouse locking tool -Changed the monitor positions in display settings -Disabled full-screen optimizations -Disabled cursor movement between displays

I am at my mental breaking point with this because it does not happen with any other game I have installed. Luckily controller works fine, but I reaaaaallllly don't like playing on controller....

Any advice or help would be GREATLY appreciated, and if anyone solves this for me I will build a monument in their honor in my realm :-)
