Unable to load epub file

[gtg2619]

Details

(process:3034): GLib-GIO-DEBUG: 13:09:42.297: _g_io_module_get_default: Found default implementation networkmanager (GNetworkMonitorNM) for ?gio-network-monitor?
[FATAL 13:09:43.696422] [GLib-GIO] g_file_query_exists: assertion 'G_IS_FILE(file)' failed
(WebKitWebProcess:3415): GLib-GIO-DEBUG: 13:09:45.249: _g_io_module_get_default: Found default implementation local (GLocalVfs) for ‘gio-vfs’

This error occurs on ElementaryOS 7.1 (stable), and I installed bookworm by following the guide in README. I also tried giving more permissions, using absolute paths #366 , opening with bookworm, etc., but none of them solved the problem.
I also tried different epub files, and I can roughly confirm that it is not caused by epub files.
This problem prevents any content from being displayed in the interface. Only the title is visible.

Thanks for the update. I'm trying to update bookworm to gtk4 and republish on elementary app center. I will keep this issue open to remind me of this problem with elementary 7.1. There has been some recent updates to flathub for the SDK. Will be great I you can try to install again and let me know
