Perseus Does not want to save file after running an R script.

[DewyTUE]

I ran the 'Remove batch effect' function via R, and it works fine, although after generating a batch-corrected matrix, I get an error when I want to save the perseus file.

Steps:
Create random matrix --> 'matrix 1' --> remove batch effect --> 'matrix 2' --> save --> error.

Error: 'Failed to write session.' and then "Type 'PluginInterop.Utils+<>c__DisplayClass2_0'in Assembly 'PluginInterop, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable"

What can I do to fix this?

Thanks a lot in advance!
