Help, errors, not working in 2.93.1

[Master-Dinochan]

Hello there, it is very useful addon but now produces error while trying to use mixed paste and mixed apply. Everything was fine on 2.93 until we updated to 2.93.1

Hope this can be fixed, the addon is very unique, but sadly the updates are very rare, it could be extended to be a part of blender's default functional.
