Impossible to generate or renew any let's encrypt certificates on Plesk Obsidian

Question

I can't create/renew any SSL certificate through Plesk panel with let's encrypt 'cause this error while trying:

" Passed 'exception' value must be an \Throwable object "

when click for adding the new SSL certificate (same result if I try with only domain or wildcard certificate).

I discover this error yesterday when adding let's encrypt certificate to a new domain created. Same thing happen when try to renew SSL on old domains certificate (actually valid until expire) .....

First time happening, what about this error ?

CentOS Linux 7.9.2009 (Core)

Plesk Obsidian v18.0.46_build1800220905.16

Thanks.
