Wappler not uploading to ftp server - winPty agent error

I am using the laster version of wappler and no can’t save to my server. When I run System Check the app is stuck checking “checking LFTP installation and version…” and won’t do anything else.
I have installed the latest version of Node.js, I have disabled McAfee, and have restarted my computer. None of this worked. On save I get an error saying that WInPTY agent. Why did this stop working and how do I fix it?

Same as before Edward:

I did disable it, and that didn’t help. BTW I am using windows 10

This id different than before, at least before I could get results when I run system check, how it just hangs up. I have completely disable Mcafee and it doesn’t help.

I found the problem, it was Malware Bites, which also has a realtime scanning feature. That was the problem.
