One fix that always works for me (fixing black screen crashes or crashes to desktop) is to reinstall my graphic driver with a factory reset and deletion of saved precepts. You do a factory reset directly at the beginning of the driver installation, and then comes the deletion of precepts.
It seems AMD's drivers have a tendency to fail if one updates them with an old driver already preexisting. Also, after Windows 10 updates, the AMD driver also fails to work many times and black screen crashes occurs. But this is usually fixed with the latest drivers by AMD fixing the issue, and a factory reset completely deletes the old drivers and saved precepts before reinstalling it a new.
I speak from personal experience and this has happened to me many times, and I would not know what to do if this fix did not work for me, and I would probably have switched to Nvidia long time ago if I could not have resolved the issue satisfactorily.
It does not hurt trying.
Good luck!
P.S.
Some reports success by undervolting and underclocking the graphics card.
Again, it does not hurt trying.
