MusicBee create tab over tab in toolbar

[Tagoria]

Hey,
i have a problem that MusicBee creates one tab after another by itself. I have now 8 tabs "Music" and 1 "Music-Explorer".
The "Music" tab is multiplying itself again and again. When i delete all except one, after some hours new tabs created.

How can i stop this?

It doesn't seem very likely that MB is creating tabs "by itself." something else must be taking place.
What version of MB are you using? (Help > About) INCLUDE THE LETTER (if any) AFTER THE NUMBER
How was MB installed? (Store, Installer, Portable)
A screenshot might be helpful here.

But that's what happend   .
I'm using 3.4.8033 P, installed on 29.01.2023 00:09:02, portable edition downloaded from here.
Up to now i can reproduce it, it just happens and i don't exactly know why, i didn't use "Add tab" to add "Music".

The errorlog file has a lot of error messages, like System.NullReferenceException. It seems that there are some nullptr.
The file is to big to post here, upload it here: https://file.io/PoDuQro4tuU5

Installation folder: e:\MP3-Datenbank\MusicBee\
Database folder: e:\MP3-Datenbank\Datenbank\
I put the database not in the same directory as MusicBee suggested.

Thanks for the additional information.

Please open the error log (Help > Support > View Error Log) and copy and paste the most recent three or four complete events here. (I typically don't download/open files from unknown sources) You probably uploaded the entire Error Log, which most likely goes back to day one. The beginning of each event entry will look similar to this:
2/9/2023 1:15:51 PM - 10.0.19045.0 - 3.5.8440.35283P

Its doing as intended - when you click on the artist/ album in the artists view, it opens the artist in the music explorer in a separate tab. If you dont want to keep the music explorer open, just close that tab.
