datefmt_create: invalid locale: U_ILLEGAL_ARGUMENT_ERROR (LocalDateFormat.php:27)

[Yoda-BZH]

When using v0.20.0 with locale C, in director -> Deployments and director -> Activity Log, I have the error:

Oops, an error occurred!

The C is my system default. The locale is not forced in PHP (8.2).

The following (temporary dirty) fix works for me:

@Yoda-BZH Yep this is less dirty than my hack. And the better right placement for this issue.
