[solved] Backend hangs when I set Themes > Folders. Why?
The backend hangs when I set Folders under Themes.
Why is that?
I do as follows, the problem is in step 2c:
In File Manager:
1a. I create a folder "themes" (directly under File system).
1b. Under "themes" I create a subfolder "theme_one".
Then in Layout > Themes:
2a. I create a New theme "theme_one".
2b. I select its Templates folder = "theme_one". Result so far: I can Save this setting.
2c. I click Folder > Change Selection, and in File Picker I select "theme_one". When I click Apply, a pop-up "Loading data..." is displayed endlessly. If I refresh the page after a while, the setting has not been applied.
This happens in version 3.2.3.

Addition:
I notice these lines in error.log at the moment I do this:
PHP Fatal error: Uncaught
