If you don't like the new 64-bit Epson scanner application for MacOS, you can run Windows on your Mac and use the good old Windows application.

Here's a screen shot from my iMac, running MacOS Catalina. The Epson scanner software is running on Windows 10, under VMWare Fusion 11.5.5.

You can also see the resulting scanned image, viewed on the Windows desktop... No problem.

I presume you can do this with with other VM tools but I happen to have VMWare Fusion. These applications are affordable and save you from having to purchase a dedicated machine to run Windows.
