Morning All,
Hope everyone is safe and well.
This might be a similar problem to the old "window behind the description dialogue" which has been much loved (!) Over the years.
The info on this link might help move the "off screen" Toad, back onscreen.
Allow to cancel Reconnect dialog using ESC - #3 by NormTeamT.
HTH
Cheers,
Norm. [TeamT]
