It is possible to drag&drop further files onto MP3tag while other file operations are on the way.
The result is an exception error.
These steps should reproduce the error:
Open at least 2 explorer windows with folders that contain files that can be editted by MP3tag.
Load a decent set of files into MP3tag. The number depends a little on the performance of the setup. The target is to start an action with the first set of files that takes a while so that in the meantime it is possible to d&d another folder / set of files onto the MP3tag files list.
When you start the action on the first set, the little message box appears: "Writing tags".
While this window is still there, drag&drop further files onto the MP3tag files list.
Observed behaviour: The mouse cursor changes to the D&D cursor and allows to drop the second set of files.
MP3tag overlays the "Writing tags" box with the "Reading files" box.
After a short time the message appears that an exception error occurred.
I would prefer it that it is not possible to drag&drop further files onto MP3tag while other processes are still running.

I've fixed this issue with the current Development Build [Mp3tag v2.87d](https://community.mp3tag.de/t/455).
Thanks for reporting and for taking the time to describe the bug in a way, that made it fairly easy for me to reproduce the issue 👍
