Node-RED doesn't start anymore

My Node_RED on Raspberry Pi doesn't start anymore.
What can I do?

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

at /home/pi/.node-red/node_modules/node-red-contrib-broadlink-control/nodes/RMNode.js:92:143
nodered.service: Main process exited, code=exited, status=1/FAILURE
nodered.service: Unit entered failed state.

The problem is with the broadlink node
node-red-contrib-broadlink-control which should handle the error gracefully. So one thing you need to do is log an issue with the nodes author to get it fixed.
You can follow a link from to the nodes github page.

Next thing is to try rolling back to your last version.
If you cd into your .node-red directory and list all the files there is a hidden file called
.flows_RasPi3.json.backup (note the leading dot)

copy your existing flows file to a new location (just to be safe) and then rename the backup file to flows_RasPi3.json and restart node-RED.

Well as you can see you have several errors there. The first is that you have two join nodes installed so I suggest removing node-red-contrib-join unless you really need it.

The next is that you have an error in function:Set maanstand.

The third, which is the one that is killing node-red appears to be a bug in node-red-contrib-broadlink-control. If you uninstall that node from the command line using

cd .node-red
npm remove node-red-contrib-broadlink-control

then restart node-red you will at least be able to get into the editor and can then work out where to go from there.

Thanks for your help.
However I had the same issue with the backup file. I had to remove node-red-contrib-broadlink-control.
