Junit 5 Run Configuration in Spring Boot Multi Module project Cannot Access Class

IntelliJ 2018.2.4 (182.4505.22)

Same in 2018.2.5 (182.4892.20)

Error screenshot:

It should be noted, DESPITE the error, we are still able to run the configured test! (just have to manually specific the full class path to the method/class, since clicking on the 3 dots button to locate it gives the error "JUnit not found in module [module_name]":

I tried things like invalidate cache and restart, "Reimport All Maven Projects" buttons, Rebuild Project...

Similar issue I posted on StackOverflow when no tests were being detected at all.

Since then I found a solution to that issue, but the Run Configuration issue still remains and co-worker seeing this as well so it is not only my IntelliJ being affected.
