Scrubbing randomly stops working in Multitrack

I'm experiencing a massive annoying bug in Adobe Audition 26.3.0.79 on a MacBook Pro (M3 Max, 36 GB RAM).

Issue:
Audible scrubbing works normally when I first open Audition. However, after working for a short time in a Multitrack Session, audible scrubbing suddenly stops working completely.

Normal playback continues to work perfectly. Audio output is fine. Only the audible preview while dragging the playhead disappears.

I can reproduce the issue after actions such as:

• Zooming into the timeline using the MacBook trackpad (pinch gesture)
• Sometimes after using Shift + Backspace ("Delete and Close Gap" / Ripple Delete)

Once the bug occurs:

• Playhead still moves normally
• Playback works normally
• Audio files are fine
• Only audible scrubbing is gone

The only way to restore scrubbing is to completely quit and restart Audition. After restarting, scrubbing works again until the bug occurs again.

This makes precise podcast editing almost impossible.

System:

• Adobe Audition 26.3.0.79
• MacBook Pro 16" (Nov 2023)
• Apple M3 Max
• 36 GB RAM
• Built-in trackpad
• No external mouse

Questions:

• Has anyone experienced the same behaviour?
• Is this a known bug in Audition 26.3?
• Is there any way to reset scrubbing without restarting the application?

Any help would be greatly appreciated.
