Inspector window "grey cover" bug

Editor Ver. : 2020.3.31f1
I got caught off guard by this bug today and I don't have any idea how to resolve.

When I click in Idle state or Run state to use the Transition space, The Inspector window (where it shows the state functions) is covered with a grey blank.


However, I created another state (Jump), and it shows its functions normally

I'm not sure if it's a bug of the project or if it's general, but I need it to resolve ASAP.

 

Hello,

You're using a bugged version of Unity, it's fixed in the latest 2020 version or 2021.

 

So I need to use a new editor version? If so, would I need to restart all the project?

 

No, your project will automatically update if you launch it with a new version. Make a backup first just in case.

 

Hey, I installed a new editor version (2021.3.3f1) and opened the project, but now it's worse
I don't even know what is wrong now

 

Well that's not good. The first bug in this thread happens to everyone, but I just tested 2021.3.3f1 and it was fine. If you made a backup of your project like I recommended, you can try upgrading it again. However, I would upgrade to the latest 2020 version for the highest chance of success.

 

Also, you should probably submit a bug report, because that's not normal.
