Null Pointer Exception on upgrade to v3.14.0

I'm getting a strange null pointer exception after upgrading to v3.14.0:

I was getting the same error and stopping the gradle deamon ./gradlew --stop fixed it for me.

[Jeremy Mailen]

Yeah @LukevanTricht please try restarting the gradle daemon. It's been notorious for caching things it shouldn't between versions, so it might be an artifact of that.

[Luke van Tricht]

Ahhh, Of course it was gradle 😅 That fixed it, thank you! Was pulling my hair out, didn't consider that Gradle wouldn't separate it's cache by version. Will keep that in mind for in future.
