Hello,
I'm not an expert with NOOBS.
But as you said, it seems to be a problem with files in the SD card.
If you want to install only openplotter on this raspberry I suggest you to use the img version of openplotter.
The procedure is really simple:
You can use balena etcher : https://www.balena.io/etcher/
You take the img version. And you just select it in balena etcher, then select your sd card and lastly you can click on the flash button.

I hope it will be useful.
