Same here. Dell Inspiron 7520. The latest AMD Radeon drive crashes Win 10. Even if I disabled the AMD card and use the internal graphic card, it still crashes out when the Windows 10 upgrade 1903 runs. So I am stuck with the old version of Win 10 :( . Can someone help?
I also have Dell Inspiron 7520 SE.
Go to safe mode, Disable your AMD graphics auto driver update from windows, and then uninstall any graphic driver from AMD in device Manager.
Use only your internal graphic driver, until AMD/Microsoft decides to fix this.
