File are not accessible after Big Sur update

I am having a problem after updating to Big Sur.
I cannot access my files, neither to those on the desktop nor in documents, after an update to Big Sur. When I check the HD usage through About this Mac >> Storage, I see that the files are there. It shows 66 GB is used (15 GB system, 51 GB Other). When clicking on manage storage, it lists all accessible files and then lists a folder name "other" 51 GB, but grayed out, not accessible.
