Hey there,
I've been having an issue since I upgraded to 5.6... If I have the playmaker editor window open and I either save any script or press play in the unity editor, the playmaker window goes blank and I get an error that repeats every frame in editor and play mode until I close that blank tab. I cannot reopen the playmaker window unless I restart unity and I already tried downloading the latest playmaker update. Any ideas? Here is the error btw:
