Description

We have an Angular 14 project and a user reported that Chrome would crash for them consistently with the 'sad tab' and error code 11 when they opened certain mat-select inputs. The affected inputs were all multiples, just like this issue.

They are running Chrome Version 124.0.6367.62 on an Apple Silicon Mac, but we have reproduced the issue on Chrome Version 124.0.6367.62 on Windows ARM also.

This issue only seems to affect Chrome, but with no obvious pattern. After a crash, the web inspector reveals nothing unusual, nor is there any console output. I was able to capture chrome debug logs during one such crash, but it did not reveal anything interesting.

I realise that this report isn't particularly useful since I can't reliably reproduce the error, but I suspect this may be happening more widely than is realised since it's unlikely to get picked up by automated error monitoring.

Reproduction

We have not been able to consistently reproduce the issue. Having made no code changes, the issue is manifesting intermittently.

Expected Behavior

Opening a mat-select multiple should not crash Chrome.

Actual Behavior

Chrome crashes when opening mat-select multiple
