Hello. I’m getting exactly same error.
I’m using Chrome 78.0.3904.108 64 bit
I tried to clear cache, reset settings etc. It seems to help temporary, but next time I connect/disconnect, use menu or whatever, that error comes up again.
Now I’m using Opera to manage mudfish. It has no such problem.
But I want to use Chrome. Please fix it (or tell us how to fix permanently)
If you want to use mudfish v5, I think Debugging issue for Mudfish v5 link is helpful too to debug your issue. Most of these issues are related with Kaspersky Internet Security.
