BoilR: Crash on selecting 'Images'

I am running BoilR on Steam Deck, with latest system software and up to date BoilR from Flathub.

The program starts fine, but when ‘Images’ is selected on the left side of the main Window, it crashes. Here’s the output from the terminal:

(deck@steamdeck ~)$ flatpak run io.github.philipk.boilr

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I’ve tried to run Rust backtrace as suggested in the error, by running flatpak run io.github.philipk.boilr --env='RUST_BACKTRACE=1' but it does not seem to work. I am uncertain if I’m not doing something right, or the error message is wrong/outdated.

Please let me know if there’s anything further I can do to provide diagnostic info.
