I am facing a few problems when I'm using Illustrator 2021
1.when I try to delete any effect in the properties panel, it will crack immediately.
2. I used to highlighting the number of sizes or positions when I need to change them. but since I updated to 2021, I'm can't highlight the number anymore, instead, now I only can use backspace to delete the number one by one and type the number back in.
Those problems only appear in my Window computer, Mac is fine
