I had same issue - MacOS 10.14.3 and Adobe 2019.010.20091. Spent weeks looking for an answer, uninstalling and reinstalling countless times, nothing worked... Until I followed the following steps:
You have to go to user > Library > Caches
and
System > Library > Caches.
and erase all files and folders in the Caches folders (I only deleted Adobe and Acrobat ones).
Attention: After that your System has to set up new Caches, this takes a while and your system is slow. Once the caches are rebuild the system is working normal again.
Restart after each of the steps.
3. Install Creative Cloud
4. Install Adobe Acrobat DC
