Broken: version: 2.93.0, branch: master, commit date: 2021-06-02 11:21, hash: 84da05a8b8
Worked:

Short description of error
Cycles render only two frames of animation when all of these functions are enabled: Time remapping (with ratio more than 1), Motion Blur and Persistent Data.

Exact steps for others to reproduce the error
To recreate this problem you need to create animation, set time remapping with ratio more than 1 (for example 60/24), enable Motion blur and enable Persistent data, as you can see in attached file.

Confirmed with attached Blend file on macOS Big Sur on MacBook M1. When I manually created a new animation based on the instructions the rendering stopped at frame 5. So the position where rendering stops seems to vary.

Maybe related to #89053, as that issue also claims to be Motion Blur + Persistent Data related.

I can confirm this issue with Blender 2.93 release and Blender 3.0 on Linux (see information below).

I decided to bisect the issue and to see if any more information could be found out. The "culprit" commit is the introduction of Persistent Data. 50782df425

I also ran Blender with the commend --debug-all and I couldn't find anything useful from it.

There seems to have been some prior problems with Motion Blur and Persistent Data: #87283, though that is marked as being fixed.

This issue is different as it's the time remapping along with motion blur and persistent data that is causing the issue from the looks of it.
