Request from non-main thread

I originally posted this here but was corrected that it belongs here. Basically it is nearly impossible for me to effectively type text in insert mode because every time a key is pressed I get bombarded with the error:

Request from non-main thread.
Requests from different threads should be wrapped with nvim.async_call(cb, ...)

currently it's unusable and can't use vim because of this error. I have done :PlugUpdate to make sure that I have the newest version, but, didn't help. This error message started today

I have closed all my terminals, restarted neovim etc. but still there.
