Cannot access web interface after upgrading from debian 10 to bullseye

Hi to all I just upgraded debian 10 to 11 and I cannot access anymore urbackup GUI.
If I try

root@backup:/home/user# systemctl status urbackupsrv
● urbackupsrv.service - LSB: Server for doing backups
 Loaded: loaded (/etc/init.d/urbackupsrv; generated)
 Active: active (exited) since Thu 2022-01-13 18:56:35 CET; 13min ago
   Docs: man:systemd-sysv-generator(8)
Process: 474 ExecStart=/etc/init.d/urbackupsrv start (code=exited, status=0/SUCCESS)
    CPU: 91ms

gen 13 18:56:35 backup systemd[1]: Starting LSB: Server for doing backups...
gen 13 18:56:35 backup systemd[1]: Started LSB: Server for doing backups.

or

root@backup:/home/user# systemctl status urbackupclientbackend
● urbackupclientbackend.service - UrBackup Client backend
     Loaded: loaded (/lib/systemd/system/urbackupclientbackend.service; enabled; vendor preset: enabled)

gen 13 18:56:34 backup urbackupclientbackend[418]: ERROR: Binding ipv6 UDP socket to port 35622 failed

so in dmesg I got this error related to libcrypto

urbackupsrv[548]: segfault at 10 ip 00007f220bac5fe0 sp 00007ffc539fa0d0 error 4 in **libcrypto++.so.8.4.0**[7f220b99c000+1e6000]

maybe is something related to libcrypto8, I checked that in debian 10 was version 6. Is there a way to fix this? I have installed urbackup from this repository:

root@backup:/etc/apt/sources.list.d# cat home:uroni.list
deb http://download.opensuse.org/repositories/home:/uroni/Debian_11/ /

I uninstalled urbackup, removed the uroni debian 11 repository, and reinstalled it from deb package suggested here UrBackup - Install UrBackup on Debian/Ubuntu it started to work again, maybe there is something wrong with the repository for debian 11, but I noticed that the version in the rep was 2.4.14.0-1 instead of 2.4.14.0 of the deb package.
