systemd hangs at reboot

[Adel Ahmed]

whenever I run systemctl reboot I get a black screen with a non blinking cursor

I can susccessfully isolate into rescue and emergency taargets, when I try rebooting there I get
started store sound card state [ OK ]

and then nothing

here's my systemctl list-unit-files:

I've had some success in tracing the problematic service
user@1000.service <1000 is my uid>

usually tries to run for a minute and times out, tried stopping it manually(not sure if that is safe) it timed out and was killed one minute later
