Rider 2025.3.1, NCrunch 5.21.0.2

Again, I have no idea when this happened or what I was doing in particular. Rider's little red exclamation mark in the bottom right of my screen often goes unnoticed for a while.

Cheers

Thanks for sharing this. This one is going to be hard to track down without a way to reproduce it. Was there any notable impact other than the error message?

BTW - For exceptions that don't require follow up and troubleshooting, I recommend using the bug reporter inside NCrunch. It should generally capture errors from the IDE (you can also copy/paste them into the description to be clear), and it will include any background data from the engine at the time the exception happened.

Cool, I missed the embedded bug reporter. Will use that.

I cant recall any impact that I noted.

It's under the NCrunch tool menu, which you can also access by left clicking on the corner spinner.
