Cant start after reboot

I have node red install in raspberri pi with openhabian with no issues in the last year but......

After reboot node red is not starting. I tried to start as a service and dont start neither
The only way to start is doing as root loosing all flows and modules installed

I thought that was a problem with the port and try to change it but didnt work neither and also check there is nothing listening in that port

Your flow is the issue (crashes when flows run)

Start node-red in safe mode, fix your flow, deploy.

Search forum or reads docs on how to start in safe mode.

Thanks for your support , I put in safe mode and start. I remove the last changes applied but still crashes , any tip for debugging?
