Node red always restarts with this error message

Hardware
1

nodered.service: Main process exited, code=killed, status=6/ABRT
nodered.service: Failed with result 'signal'.

How can I fix it?

Runing on rpi 4 64 bit

2

How did you install node red and how are you starting it?

What do you see if you run
node-red
In a command window?
Copy/paste the output please, not screenshot.

Can you start in SAFE - Mode ?

i found that the flow below killed node-red.
It seems that 6 template nodes within this flow are responsible for this crash.
I tested it with 2 and it worked but with 6 it crashes.
please have a look at these nodes which have styles.
As I am am not experienced with CSS thats most probabely the reason for the crash.

I will try again

  1. How did you install node red?
  2. How do you start node-red normally
  3. I should have said what do you see if you run node-red after stopping node red. The port not available message is probably because node-red is already running. Please do this with the failing flow so we can see the error that causes node-red to restart.

Hi Colin,
thanks for your support!
It is runing now. I migrated my application from my old RPI with dashboard 1 to a new one with dashboard 2. Then I copied my flows to the new one. Unfortunately I copied the template nodes as well and I think they did not work with DB2 and crashed. I rewrote this specific flow with DB 2 template nodes and now it works.
