The same problem was reported yesterday:

At the same time a related kernel problem was reported:

Hopefully this will be fixed in the next Ubuntu kernel update 5.0.0-21 but in the meantime use kernel 5.0.0-20. If you want to avoid reinstalling Ubuntu you can manually install the previous Linux Mainline/Stable kernel with these instructions:

The kernel before 5.0.0-21 in Ubuntu Speak is 5.1.16 or 4.19.59 in Linux Speak. When looking at the mainline kernels the important thing to remember is the dates. Anything dated July 21-23 is new one with bugs, anything around July 14 is the previous version:
