Unplugged NAS w/ RAID 1, Help Repairing Storage Pool

I’m hoping someone with more technical knowledge can help with my issue. my Ugreen NAS got briefly unplugged during use. I have about 4.5 TB of data on one drive with a RAID 1 backup on the second drive.

When the NAS got turned back on, I got an alert that my storage pool is degraded even though both of my drives are fine. It is telling me to repair my storage pool via Hard Drive 1. However, when I tell my drive to begin the repair storage pool function, it attempts before saying my request has timed out and to try again.

Does anyone know how I get the “Repair Storage Pool” task to actually run? I’m a little freaked out, because I don’t want to lose all my data. Please respond if you know what’s up!
