Unfortunately, release 8.0 exposed a crashing bug in the plugin, seen most often when working with UVM projects. Not an expected or acceptable plugin behavior and I apologize for letting it slip through. Will pay more attention to occasional crashes going forward.
The only good news is that this solution solves a lot of occasional crashes. The cause was the Compiler Directives logic breaking against the @NotNull identifier contract. The answer is to modify contract and code to handle null for any identifier.
I have asked JetBrains' for expedited approval and hope to see the fix released shortly! Will update this post when they do.
Please keep reporting issues!
