Passolo 2022 SR 1 and .Net add-in

Dear community, 

I have just updated to Passolo 2022 SR1. Upon starting the program it prompts the following message: 

ERROR - Cannot load add-in C:\Program Files (x86)\Trados\Passolo\Passolo 2022\System\DnDotNet\DnDotNet.dll
The add-in has another interface version.
Setting load type to "Manual" 

How can I fix this? Do I need to roll back to the previous Passolo version? 

I do not have a support agreement.

Thanks for any help.
