Hi all! I was having the same issue and discovered that there is a known bug that was introduced with macOS 11.2 for the SoftRAID app. This bug prevented the driver from loading on M1 Macs. The fix is actually simple and relatively painless.
If you've got macOS 11.2, upgrade to 11.3 or later (current latest is 11.4) and download SoftRAID 6 from from https://www.softraid.com/. It was free update for me as my OWC drive came with SoftRAID 5, but otherwise it costs $$.
