@LiquidTension @tetonbob @Homer712 thank you for your posts and because you had I went through the ordeal to get into the forum and provide an update based on my experience.
I am running Malwarebytes version 4.1.0.56, Update package version 1.0.21318
My 1Password update today was to version 7.4.759
When I updated to the previous version (after March 10 and prior to today) I just shut down Malwarebytes completely to complete the install just like you did and then I found your post. So tonight I played wack-a-mole and was successful in updating 1Password with the Ransomware Protection turned off.
things that make you say hmmm.
Nwfandi.
