Snapshot cannot be named while saving in ACR 17.1 with MAC OS Sequoia

This SEEMS to be the case BECAUSE of the default naming convention when saving the snapshot—I believe using what are now, what must be, illegal characters in the default save-name, e.g., "2025-02-11 15:58:49".  See screen shot below.

I CAN RENAME all previous snapshots, but never rename the new (illegal character) snapshot.
