Is there a way to clear stale RUN menu entries

I just installed Big Sur and want to know if it's been tested

My Archive Shows Some Icons for the folders and files.
But some are blank! I do not know why the icons disappear,
sometimes they reappear. I hope this is only cosmetic!
Any fixes?

I have a dual boot hackintosh+win10 and I am very much concerned about preserving my EFI partition
I wanted to know if QRecall can be used to cover this issue?

How does QRecall handle the EFI Partition of the disk? What strategy should one follow to backup the EFI Partition?
