If your Mac is on a network where it does not have Internet access, Adobe Acrobat Pro crashes. If you start the program, the Apple Beachball appears after about 5 seconds and the program is no longer usable. It seems that Adobe Acrobat tries to log in with the user account, but this is not possible due to the lack of Internet access.

I have installed the latest MacOS version (10.14.3) and also the latest Acrobat Pro version (19.10.20091.315611).

I was also able to reproduce the problem in another network and with a new clean MacOS on another computer.
