This is on a Windows box but I'm 99% certain I had the same problem on Linux on another box trying to run the same version (can check if needed).
Same issue with 2.37
¿Why didn't you try to read the error message before opening the issue?
It's telling you that it can't find a file that Windows usually has => mscorlib.dll. Just download it from somewhere.
The plugin is works fine with Keepass 2.36 & 2.37.
