Thumbnails are not updated and images cannot be exported.

Also, the 2d view is not updated even though the display output is pressed in the 2d view.
You can't even export images.
I tried reinstalling it and clicking Recreate Thumbnails, but it didn't work.

It's been working fine until now, and when I put together a heavier and more complicated node than this, it worked fine, so I don't think there's a problem with the computer's machine specs.
Please let me know if there is a solution.

You appear have an error in your graph - see the red dotted line in the first screenshot which shows you have a greyscale output from a node connected to what looks like the color input of another node.

Outside of that have you tried right clicking in the grey area of your graph and using Clear node thumbnails (F5) followed by right click and Compute node thumbnails?
