Problem with Gridder instrument on MacOS 15

[RedstoneBeat]

In Logic 11.0.1 the plugin is shown as validated and activated in the plugin manager, but does not appear in the instrument selection. The MIDI and effect plugin, however, works.
It works under Ventura with the same Logic version.

Same, On OS 15.2 Logic 11.1.1, Validated but doesn’t show as instrument. Effects and midi fine. Blue cats patchworks will work if you load the vst3, can load au with same, but bad noise…
