ePSXe can't view files via "run game"

I'm running on a Pixel, Android version 7.1.

For some reason, whenever I go to "run game," I can't view any files. The file explorer works just fine when trying to select a bios, but shows nothing when trying to select a game.

I just installed it so it should be the most recent update. I've tried reinstalling. Storage permissions for the app are turned on. I can't find anything via google.

Any idea for how to fix this?
