Whenever I try to manage Plugins using right clic => plugins or write plugins it doesn't work.
I'm experiencing the same issue, and the same error-trace exactly.
Cerebro version: 0.3.0
Try latest version from https://github.com/KELiON/cerebro/releases
Pretty much a duplicate of: https://github.com/KELiON/cerebro/issues/457
Not the same OS. Maybe a different cause so.
I think that the download link at https://cerebroapp.com/ should be updated. .exe download is a link to 0.3.1.
Edit : 
It look like update don't work
edit 2 : more bug 
Is development dead?
@zbhoy I aws a bit busy during last several months, but I'll try to check and fix all active issues 馃挭
@KELiON Totally understand! Glad to see you are back. Been using the app even with the current errors because I haven't found anything better
