Welcome to the forum.
Please stop node red and start it again in a command window and post the full output here.

The full log from the startup command that you type. Even knowing how you start node-red may be important.

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.

I suspect the problem may be caused by having spaces in the folder name.

Or it might be related to

Which may be because that node has not been updated in 5 years so may not work any more. Try uninstalling that node, restart node-red, and see if it fixes it. Always fix the problems that are easily sorted before worrying about the more difficult ones.
