Trouble running on Raspberry Pi 4 64-bit

OK, good news

I've updated the archive of the latest version (the size in the website is not reflecting the real size in this case)

Thank you - I will try it later.
The previous version is working very well and I am exploring the program

Hello, I just tried to upgrade to release 5.10.15 (RPI Bullseye 64) but got also get same issue than described above. QtVlm won't launch anymore.  I did extract all files as below: 

No errors messages, the sandglass timer will stop after few seconds.
Few weeks ago when I upgraded to previous release (5.10.14-P4) I had to re-install the complete package to get a release that will launch... 
Thanks for your good advice,
BR, Yannick

When trying to install complete new package , error message was :"./qtVlm: error while loading shared libraries: libpulse-mainloop-glib.so.0: cannot open shared object file: No such file or directory"
Issue resolved after installing library "libpulse-mainloop-glib0-14.2-2+rpi1 (64bits)
Upgrading of previous release also revolved.
