What happened to the TAB button?

I found that the Tab key behaves similarly to pressing to focus a textbox like TextInput, even though it isn’t there at all.

But this problem only affects exported games. In Gdevelop, the preview works normally.
I tried going back to my old game. I found that all my games Have the same problem. New projects and game example available on Gdevelop have the same problem.
Consider sending my game to others to test. The results are the same.
I have tried reinstalling Gdevelop but the problem is still the same.
Now I’ve tried creating a small project. that has nothing To make the information as narrow and easy to see as possible, let’s make it easy for everyone to see.

This is this project. which I have exported ↓↓↓↓↓

This is all in this project. ↓↓↓↓↓
