Hi,
Make sure from the system if the plugin assembly is uninstalled correctly, you can try searching the plugin assembly into the CRM database table or can rename the namespace of the Plugin Assembly and rebuild it. You can execute the following select query
on CRM database to retrieve all plugin assemblies information.
SELECT [Path]
,[Name]
,[Version]
,[VersionNumber]
,[PluginAssemblyId]
,[PluginAssemblyIdUnique]
,[PublicKeyToken]
FROM [PluginAssemblyBase]
