Moon+ Reader PDF blowing up

[BillSeitz]

I have a 25MB PDF I'm trying to read.

It was going fine until I toggled from raw-text to scan-view mode (not sure if those are the right words).

I first his this on my ChromeBook. The current state is that if I open that book, I briefly see the scan-view, then it "crashes" and returns me to RecentList. I've rebooted the tablet and made this my first action, so I have max memory, but it hasn't helped.

Then I tried loading the book onto my Pixel6, in hopes that I could clear something in the book-state... unfortunately clicking on the book goes straight into the scan-view. The only difference is that it automatically retries/recrashes a bunch of times, before the app itself dies.

On both platforms I've tried tapping multiple times on the screen while the app is working, to try and change the render-mode, but I never get that button to pick. (And even if I get chapter-list button pressed, that view starts to open up but then the app dies.)

Do I need to wipe out the highlights/setting file for the book? How do I even do that on Android/Chrome where many files types are rather hidden?
