SharePoint Online Update just released? Web Part Font Glitch

I was searching for any notes on recent changes that Microsoft made to SPO, and I was unable to find any. I noticed they've updated the styling of the icons on the text editor, plus they added the Copilot button. 

There is a new glitch where if you select some text, and try to type a manual font size it will break and default the text to the smallest font (10pt). This is extremely problematic for me as I have tons of pages I've just finished standardizing with size 50 font which is now impossible to set and use.
