the list of folders on the left side of the screen is no longer visible. I tried updating to v. 102.3 but it didn't help.

I have a new laptop and migrated my files to it. I can open Thunderbird and the messages are still there, but the list of folders on the left side of the screen has disappeared. The folders are still there, and I can guess which one I want and click on it, but I can't see the list any longer.
