Blender send2ue Plugin rpc error

I have a problem with the “send2ue” plugin for Blender. I use version 3.2. I did the setup in Blender and Ue and have a mesh in the export collection. When I press Export → send2ue comes the first error. When I click Utilities → Start RPC Server, the 2nd message comes up. How can I fix this?

same error here… can’t figure it out yet…

I switched to an older version of Blender. This worked for me. At the time I posted this error the new Blender version was only a few days old. Currently I use Blender version 2.93 and everything works fine.
