Research direction
Start with journalctl.txt and nvidia-bug-report.log.gz, then inspect the reported kwin_wayland semaphore block in nvidia_modeset on kernel 6.19.14-arch1-1. The issue provides no reproduction steps or test; done would require reproducing the intermittent Wayland freeze and identifying the nvidia_modeset deadlock.
