Librera Reader crashes unexpectedly

Hi there! I'm on Android 15 with a Samsung 22 Ultra, running with Kiss Launcher. I use Librera Reader (Version 9.0.5-fdroid (6294)) on a daily basis, with a library of more than 3.000 PDFs. But for the last couple of days, it crashes unexpectedly, regardless of the file I'm viewing. I cleared everything, deleted it, rebooted the phone, and the problem persists. I couldn't find relevant info on Github.

If anyone had an idea, I'd be very grateful!

Thanks.
