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.

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
Okay I just restarted the Pi and then the installation restarted and now it worked. I started node red in save mode and now the interface loads again and works. Big thank you !!!
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.
