incompatible plugin since keepass 2.57.1

Hi, i cannot use KeePassRPC v2.0.2 with Keepass 2.57.1 or newer. At the start there is always a popup message, that the plugin is incompatible. I use KeePassRPC v 2.0.2. I had this issue with a several plugins, when i installed a new version of these some plugins the error disappeared. I already updated .net. When i install keepass 2.57 with older plugin versions everything seems to be fine. But on newer laptop installations i also get the error message with new installed laptops (old keepass an old plugin version). i dont know why, but when keepass is new and plugins old, the error still exists. When keepass is old and the plugins new the Incompatibility error also exists. Any hints, what i could do?

I have the following log information:
