It works fine in the morning and then all of a sudden, it never attaches.

Log from window output

[2021-06-04 15:12:28.771] [renderer1] [error] custom request failed: Error: custom request failed

In the particular log you attached it looks like there were no tests to run; the runner didn't load any files outside of those included in unit.js. Maybe this is because the compilation was out of date, or the grep didn't find anything.

Fixed it so we wait for breakpoints to verify, not just the session. Still get renderer crashes, but this fixes the particular issue.
