Kdenlive AppImage 23.08.3 doesn't want to start

Hi, could please help me? I’m writing from Italy, sorry for my not so good english! I’m in a Linux production machine with LMDE5, kernel 5.10.0-26-amd64. I’m trying to run the newest AppImage version 23.08.3 (the last I’m using is 23.08.1) from terminal and this is the error message:

same error with version 23.08.2, and I can’t use the last versions.

Note: I’ve tested on LMDE6 and it works. Mint has certainly added or updated the libraries used by Kdenlive 23.08.2
Is it possible to resolve the issue in LMDE5?
Thanks!

Same issue, it works ok in the flatpak version – but I prefer to run appimage.

I really don’t want to try to upgrade my linux version. The one I run has been so stable.

Good luck
