Access 365 Fails To Recognize Linked Databases

Access 365 functions perfectly in Windows 10 on my laptop. I have 3 databases which are linked:

Database 1, object file (tables, queries, reports, forms & brings up main menu with icons)

Database 2, data file (administrative info)

Database 3, data file (business activity data)

The object file opens in my newly purchased Win11 desktop (fully updated) but will not recognize 2 & 3. Icons are inactive and will not open up any templates or other features.

All the trust settings are identical on both computers.

All 3 databases are identical on both computers. 

I do get the following error message "The active content in this file is blocked..." when opening the object file. BUT, all the trust settings are identical on both computers ecept for "Trusted Publishers". There is no information listed in my Win11
