Bug description and reproduction steps

I can't add a playlist. Even if I try to add it, there is no input. The cursor does not blink with a left click, and the cursor is created only with a right click, but it has no effect. Please help me.

Do you have entered a playlist name in the textbox?

I can't entered textbox.
It was not entered no matter how much I pressed the keyboard.

• I add it because I think it will be helpful, the configuration GUI is displayed like this.

++ It works fine in other versions, but when I click on the playlist I added there to use in this version, nothing works.

I thought it was a conflict between modes, and I deleted some modes. Then surprisingly, it worked. I'm sorry to surprise you all of a sudden.
