No problems with VisualVM 2.2 on my M1 MacBook Pro using the Temurin-23.0.2+7

be the only place to get it now. It did not come bundled with any JVM version -
I find it odd that yours did.

having to enable anything when I first installed version 2.1.10 a couple of
months ago, but I didn’t take any notes, so...
