An exception occurred while invoking executor 'executor://nunit3testexecutor/'

Upgrading NUnit3TestAdapter to v5, I get:

Error: An exception occurred while invoking executor 'executor://nunit3testexecutor/': Could not load file or assembly 'nunit.engine.api, Version=3.0.0.0, Culture=neutral, PublicKeyToken=2638cd05610744eb'. The system cannot find the file specified.

@thomhurst I'm moving this to the nunit3-vs-adapter repo. Can you provide some more information about your setup - e.g.

• are you running testes from the commandline or via an IDE
• I assume that you don't have any references to nunit.engine.api, but this comes from the NUnit3TestAdapter
• Can you provide a minimal example

I'm unsure if it helps in this case, but it helps to remove cache data and old build output e.g. via git clean -xdf
