According to Microsoft, the “This PC can’t be upgraded to Windows 10” error message shows up on PCs that have an external USB drive or SD memory card is connected. Inappropriate drive reassignment during the installation is causing the issue.

And if you are getting the error while trying to perform a clean install of Windows 10 version 1903 using a USB drive or SD card, copy the installation media files from the USB drive to a local/internal drive and then start the installation from the local/internal drive by running the setup file.
