Well that is a new one, I have never seen that before. What does this command show?  
`ls -al /home/canpi/.node-red`

Also what happens when you try to show the editor.

I don't know what you mean by that.

Oh, you mean it just says loading.

What did you do at the time it stopped working? Did you install a new node type for example?

The obvious solution is to restore from your last backup, but presumably that is not an option or you would have done it already.  
Start node-red in safe mode using  
`node-red --safe`  
That starts node red but does not start the flows. That will tell you if the flows file is seriously damaged.  
You can then edit the flows and it wills start running when you deploy.

When posting such output please copy/paste the text rather than screenshot. So we can copy bits out of it if necessary.

Post the log that it tells you about. When posting use the `</>` button at the top of the forum entry window to stop it messing with the format.

Edit: Before doing that run  
`sudo apt update && sudo apt full-upgrade`  
to make sure your system is up to date. Check that does not show any errors.

I suspect the SD card is damaged. Start again with a new card. Always use good quality cards from a reputable supplier.

This is very strange because the SD card is from SanDisk and I just bought it new and set it up last week.  
Can I backup the flows that I have programmed? if yes how ? would reformat the sd card

To backup your flows in case you get into trouble again, backup the contents of the .node-red directory except for node\_modules. If you have to restore, then after restoring the folder, go into .node-red and run `npm install`. That will install any extra nodes you need.
