ECS stress test fails non-deterministically

[RiscadoA]

Description

For an unknown reason, in some runs (not very rarely) the macOS action fails while executing the stress test.
It's unclear whether this also happens in the other operating system actions.

It's very weird that it doesn't always happen, as the stress test seed is fixed - all runs should perform the same exact actions.

One possible explanation could be the ECS having UB in some very specific scenario, like accessing uninitialized memory, and working only when that memory has 'well-behaved' values, like 0, or something.

Probably the first step to solve this would be to improve the error logging on this so that we get more information on what's going on.

The error we get is:
