Tonalic ARA Preview Not Working in Nuendo 15.0.30 (macOS)

Nuendo
1

System:
Mac Studio (M1 Max), macOS Sequoia 15.7.7
Nuendo 15.0.30
Tonalic ARA 1.0.2.009

Issue:
Tonalic ARA produces no Preview sound in Nuendo 15.0.30.
Preview animation runs, but there is no audio and no meter activity.
Audio is heard only after dragging the performance to the timeline.
Important:
The same Tonalic ARA version on the same Mac + OS works perfectly in Fender Studio Pro 8.
This indicates a Nuendo‑specific ARA Preview routing issue.

Request:
Please confirm whether Nuendo 15.0.30 has an ARA Preview routing issue on Apple Silicon + Sequoia.

In the Cubase forum someone wrote switching the engine to 32 bit float calculation works as a workaround.

Tonalic ARA Preview works in Nuendo 15.0.30 only when Processing Precision = 32‑bit float.
With 64‑bit float, Preview is completely silent.
So the issue is in Nuendo’s 64‑bit ARA preview routing

There is also a problem with Melodyne in ARA mode. It throws an error when loading, and later it is missing from the ARA menu on OS Tahoe in native mode. This is really, really frustrating when you have a mountain of projects to finish, and these gentlemen are too slow to fix it as soon as possible.
