All PHP-FPM versions down

Moing Everyone,
I did a DA update last night if I remember correctly and woke up this moing to PHP-FPM 7.4 down, so I did a quick reboot and then all of them went down. The following error is -

[23-Dec-2023 11:49:33] ERROR: Another FPM instance seems to already listen on /usr/local/php81/sockets/webapps.sock
[23-Dec-2023 11:49:33] ERROR: FPM initialization failed
[23-Dec-2023 11:49:38] ERROR: Another FPM instance seems to already listen on /usr/local/php81/sockets/webapps.sock
[23-Dec-2023 11:49:38] ERROR: FPM initialization failed

Does anyone know what would randomly just cause this and how to fix it please?

Thanks
