Can't delete a music file that has a "weird" character, and it messes the albums on the watch

hi,

I uploaded to my Fenix 6X mp3. One of the files had a character that appears as a ? in windows (see the attached - I guess some high unicode). On the watch, the album with this file appears, but I cannot drill into it, but even worse - all the albums after it messed - If I'm going to album B, I'm getting songs of album A, going to album C, I'm seeing files from album B, and other weird phenomena.

Now it would be fine if I could delete this file and album, but I can't - from Window's explorer (going to the watch's drive) it gives an error when trying to delete the file / album, and also from Garmin Express - it just cannot access not delete the file or the album. So it's just stuck there messing my library...

Any idea how I can get rid from this file / album on the watch, preferably without resetting the watch? I tried restarting the watch and reconnecting it to the computer

Thanks!
