Permission denied to access Microsoft Word Files

I recently encountered a permission denial to access several files in Microsoft Word. After fruitless efforts to gain permission by attempts to revise system settings (Windows 11), I stumbled upon an article that suggested I check my anti-virus app because some blocked access to specified apps. I checked the settings for AVG and indeed that was the case. I do not know how it happened but when I unchecked Word from the blocked apps, my problem was fixed.
