Faileds "systemd-sysctl" on boot

I'm getting a failed service for systemd-sysctl on boot. Bellow are some outputs.

sudo systemctl --failed

There seems to be a some problem with writing 0 to bpf_jit_enable. I've tried to echo the value manually with   echo 0 >/proc/sys/net/core/bpf_jit_enable    but get "bash: echo: write error: Invalid argument" in terminal. Has anyone else come across this.

Thanks
