I don't have any security or anti-virus software installed. I am thinking it's just a bug of some sort, may need to reinstall.
I do believe Defender comes packaged in with Win 10. May want to check that that isn't doing anything. I think you can only disable, but not uninstall that.
From what I'm seeing at the top, I doubt that it's a bug, just may not be able to get connection with what it needs to connect to. Most commercial software that I'm aware of has this type of "popup". On mine, it's when opening, but I guess it depends on what the vendor favors.
One concern that I would have with doing a re-install is won't you loose a "seat" to X8 when doing that? I know Painter you are able to deactivate and reactivate, but I don't think DRAW has that ability.
