Kile gives a SIGSEGV (Address boundary error) after updating system

Help
1

I cannot open Kile after updating my system. I can file a bug report if needed. I have Kile 2.9.94-3.1 right now. It used to open without any problems before. If I invoke Kile from fish, I get fish: Job 1, 'kile' terminated by signal SIGSEGV (Address boundary error). I don’t have any issues with Kate (version 26.08.0-1.1) and Okular (version 26.08.0-1.1). My KTextEditor version is 6.29.0-1.1.

Operating System: CachyOS Linux
KDE Plasma Version: 6.7.4
KDE Frameworks Version: 6.29.0
Qt Version: 6.11.2
Kernel Version: 7.2.0-1-cachyos (64-bit)
Graphics Platform: Wayland
Processors: 4 × 11th Gen Intel® Core™ i3-1115G4 @ 3.00GHz
Memory: 12 GiB of RAM (11.5 GiB usable)
Graphics Processor: Intel® UHD Graphics
Manufacturer: Acer
Product Name: Aspire Lite AL15-51

Edit: It seems that the Kile and Okular interaction is causing some problem. Downgrading Okular to 26.04.3-1.1 solves the problem.

i have had the same issue in arch, and grabbed a partial gdb backtrace

the issue is also fixed by using okular-git
