I have seen other posts about this exact problem, Driver incompatibility for Memory Integrity but when you click "Show" (or whatever the exact process), a blank space.
Here's my driver info. (I added the TXT file to Filebin, but I can paste the content if needed.)

I support many client machines and I never saw the issue on a new Dell - same with another fellow who seemed to only see this on older migrated 10->11 Dells and I have a good idea why. But you are the first person reporting that no driver is listed in a fairly new Windows 11. I'd still venture to guess it is Dell installing an old addon from old software whose certificate has not been updated. Can you post the output of:
