Frequent Critical Events on Dell Mini Tower 3910

Hello,

Two weeks ago, my Dell Mini tower 3910 started showing frequent critical events in the reliability monitor-Microsoft Storage Spaces SMP stopped working. This happens once or twice a day. It can occur by itself or with another fault. I'm at a loss to determine the cause.

I back up with Macrium twice a month, use Malwarebytes Premium services., have no infections, items in quarantine or other significant problems.

Is this a known defect? Is there a solution?
