On my RPI 4B the IR Remote also stopped working after upgrade to LibreELEC-RPi4.aarch64-13.0-nightly-20240614-18becd8
Analyzed the issue a bit and it looks ir-keytable does not see the rc0 device anymore but rc1 instead in my case.
 ls /dev/lirc*
/dev/lirc0  /dev/lirc1  /dev/lirc2

As the default device is still /dev/lirc0, then some commands like irw does not work.
 cat /etc/lirc/lirc_options.conf
# These are the default options to lircd, if installed as
# /etc/lirc/lirc_options.conf. See the lircd(8) and lircmd(8)

The  /etc/lirc/lirc_options.conf file is read only and currently I don't know how to easily change the device configuration to /dev/lirc1 as the shadow file in /storage/.config/ folder did not help.
But maybe it's a wrong way anyway...
