Raku Comma IDE on MacOS won't start

Question

I made some progress from this previous question, No matching VM found when running Comma IDE on macOS, but have run into a new error:

Internal error. Please refer to http://jb.gg/ide/critical-startup-errors

This is macOS Catalina Intel 10.15.7, latest CommaIDE for macOS:

java version "16" 2021-03-16
Java(TM) SE Runtime Environment (build 16+36-2231)
Java HotSpot(TM) 64-Bit Server VM (build 16+36-2231, mixed mode, sharing)

Comma needs that to be major version 11 (because the underlying IntelliJ platform also requires that). The Corretto 11 distribution is probably a good bet.

To avoid folks having to worry about all of this, Comma also bundles its own private JRE. Unfortunately, some recent releases had a problem with that bundling on Mac. It was already rectified in Comma Complete 2021.03 (the commercial version), and the fix will appear in the free Comma Community in 2021.04.

I have upgraded to Comma 2022.02 (Build #CP-213.5744.3, built on February 28, 2022) - that resolved this issue and now works well. This is managed under File > Project Structure > Project Settings > Project SDK > Add Raku SDK > /path-to-your-raku-install/bin/... You have to select the "bin" directory that contains the 'perl6', 'raku' and 'rakudo' commands - on my machine this is ~/rakudo/rakudo-moar-2021.10-01-macos-arm64-clang/bin/rakudo. [For the Package Manager setting you need to select the 'zef' command file itself.] thanks @jnthn – librasteve Mar 23 '22 at 07:49
