I've had the same problem. What fixes it for me is to reinstall the latest driver with a factory reset and deletion of saved precepts. I can always fix my black screen crashes in this way.
You do a factory reset / clean install in the beginning of the AMD graphics driver, and after this, let saved precepts be deleted.
Note: and this is important. After the first reinstallation and restart of your computer, if you are lucky, the black screen issues may be resolved. If not, black screen crashes will continue. What to do then is to reinstall again with a factory reset and deletion of saved precepts and restarting the computer. This reinstallation for me has always fixed the black screen issues for me, and sometimes I have had to reinstall up to three times after each other before finally, the black screen crashes went away.
For example, just yesterday I had to reinstall the latest driver because of black screen crash issues after updating Windows, and I could not fix the issue with the first reinstallation, but had to repeat it one more time, and then it finally worked. I don't know why.
Note: I have had to reinstall the driver in this way for up to three times before the black screen crashes went away, and it may be similar for others, so it does not hurt trying doing it even more times if your issue is not solved.
