Don't open launch node-red

I am new to node-red and using the telegram packet but when I start node-red I have the following error:

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials

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.

How can I fix it?

Also, I need to be able to save the project I started but since I can't enter the launch I don't know how to download it.

Please help.


Your flow is here...

This has been discussed many time on the forum and is found elsewhere with a quick and easy search...

Have you tried alternative telegram nodes in the pallete? I have used another one with good success.

Lastly you can launch node-red with the command line parameter --safe as is mentioned here...
