EPUP reader on Windows?

I'm aware of options for Mac, IOS, and the Bookshare online reader, but what about a desktop Windows app? It's amazing that EPUB on Windows is still so iffy and problematic.
I've never actually needed to read an EPUB, but it does appear to be gaining traction. An author once sent me their University Press-published book as EPUB, for instance.
Here's what I've tried today:
* Thorium: appears to be a web wrapper.
* Dolphin Eazy Reader: the document reader is a total keyboard trap. The app's own shortcut keys don't work while in the document view, and I have to be in browse mode to read anything. I have to use object navigation to get to buttons/menus or press alt+space, which is the only thing to escape the trap AFAIK. I wish this worked better, since it appears to let me read Bard books on the PC.
* Q-Read: Firefox warns me that it's a malicious site.
* Bookshare web reader: Sure, but it can't load what's on my computer.
* Edge. Microsoft no longer supports EPUB natively.
