I know this has been reported and supposedly fixed, but not for me. I have no .laccdb files , so that isn't the cause. I just reinstalled Microsoft 365 so now using Access for Microsoft 365 MSO (Version 2203 Build 16.0.15028.20152) 64-bit. I've spent a whole day trying suggestions found online, then from Dell support and then being transferred 4 times at https://support.microsoft.com/contactus. All suggestion welcome!
