Description
After upgrading from version 2022.2.622 to any newer version, the form's designer may not be opened even though the correct assemblies are referred in the project and the license file is deleted.

The issue has already been addressed and a fix was released in R3 2022. The CreateAdapterMethod property is not serialized any more. However, all broken resource files need to be manually handled and delete the serialized CreateAdapterMethod property from the .resx.
