Are you interested in contributing a fix?

No

Start at SelectionWand.java:93, where the stack trace shows a null actor during the /brush biome command, then trace the calls through LocalSession.java and BrushCommands.java:1595. Reproduce with /brush biome cyl minecraft:cherry_grove and verify that the command no longer throws a NullPointerException and applies the biome brush to the wooden axe.
