FYI after the upgrade from nightly-20241025-9f8eeb6 (RPi4.aarch64) to nightly-20241029-81a82b6 the PVR client (Tvheadend HTSP Client) couldn't run anymore. I suppose the plugins for RPi 4 are waiting for compilation. The revert to nightly-20241025-9f8eeb6 fixed the issue.
Edit - the same issue even after the upgrade to LibreELEC-RPi4.aarch64-13.0-nightly-20241030-2f39556 which appeared in download section in the meantime.
