Welcome Rob. I'm afraid that you need to give us a lot more to go on. For example, what is producing that error or at least, where are you seeing it?

It appears to be an error with a specific node. You may need to raise an issue against that node so that the author can respond.

Is there a way not to lose everything if I uninstall and reinstall it. Should I just restore my back up of ha?

Start NR in the safe mode` node-red --safe` and remove the node's that will give trouble

I can’t get anything to work. I can’t get safe mode to start either. Is there no way to just uninstall everything and start over? Why is it when I uninstalled it I just can’t get a fresh install. It keep trying to load old stuff.

Possibly you uninstalled the software (which was probably not necessary), but did not remove the flows, installed nodes etc.  
How are you removing and installing node-red?

I just uninstalled software. I am Kinda new to this so I am not even sure I did the safe mode correct. How do I uninstall the nodes and flows?

That tells us nothing. What do you mean?  
We have no idea about how your system is setup so we can't advise how to fix it. So tell us how you installed node red and how you tried to uninstall it.  
Also, how do you normally run node red?

I have node red installed on home assistant. Apparently something happened and it can not get to to web ui. It appears it is running in background but I can not access it. I have tried uninstalling it from the add ons in home assistant and starting new and fresh install. I have no issues in redoing all my flows. I just want to be able to access it again. When I go to start node red it will not even start or create a new log. I am sorry I’m frustrating you but this came out of no where. I have been using node red for about 2 months and have had no issues till today. All I did was add a current scene node.

You should have mentioned that as it makes a huge difference to how the problem is to be solved. The node-red setup under HA is completely different to a normal install, and few here use HA so you will probably be better asking on an HA forum.
