Not sure if this related, but you wouldn't happen to have Citrix Workspace App installed, would you?

If so, there is a known issue with Citrix that could be the culprit... see

Toad Editor behaviour copy paste ctrl chars

I am using Toad for Oracle v.13.3.0.181 when I use CTRL C or V (or other CTRL commands) in the editor they work but as soon as I type the next letter or hit return the letter from the CTRL command is pasted. Example: CTRL V will paste whats in my paste buffer + the char "v" when I press space or return or type a letter. Any ideas anyone?
