Comment:

 Thanks for the report @isgroup. This sounds like a pretty serious problem
 with the hosting environment because all manner of CSPRNGs and related
 cryptographic functionality relies on `/dev/urandom`.

 * What is the use case for running a system where `/dev/urandom` is not
 available? What is the source of randomness in this case?
 * Which version of PHP are you using? The PHP documentation implies that
 this error should throw an exception when using PHP 8, but it's not
 entirely clear.
