System Information
Operating system: macOS Monterey 12.3
Graphics card: Apple Silicon M1 Max

Blender Version
Caused by 0a32ac02e9

Short description of error
Trying to render even the simplest animation (a cube moving up, 250 frames) through "Render viewport animation" gets stuck at about frame 25. The cursor changes to a weird box shape, and the whole process gets stuck, seemingly indefinitely.

Exact steps for others to reproduce the error

Open Blender
Create a simple animation (cube moving up for example)
{nav View > Viewport Render Animation}

Hi, thanks for the report.
Probably the same problem as reported in #96370 and #96471
Do you have Adaptive Subdivision option enabled?

No... This is the default blender file. Haven't changed any setting

I can confirm the problem.
The code gets stuck in BLI_condition_wait inside schedule_write_result.
If you add a breakpoint right after that, strangely the render continues for a little longer.

It is a regression introduced between:
