Hi all

I came across this error when I tried to open task configuration after I applied RT kernel. Doesn't matter if I logged in or logged out, I still can't open my task configuration. Any ideas why?

RT kernel details:
version 5.10.63-rt52-v7+ #1 SMP PREEMPT_RT

/etc/systemd/system.conf:
RuntimeWatchdogSec=10
ShutdownWatchdogSec=10min

/boot/cmdline.txt:
dwc_otg.fiq_fsm_enable=0 dwc_otg.fiq_enable=0 dwc_otg.nak_holdoff=0

/etc/init.d/codesyscontrol:
do_status
if [ $? -eq 0 ]; then
rm $PIDFILE
echo "Error: Failed to start codesyscontrol"
exit 1
else
##############################Modified for RT kernel 15/10/2021

echo "codesyscontrol started"
fi

The only workaround so far is to use my previous saved file.
