Hi, could you provide a reproduction on Stackblitz ?

Sorry. Its a huge project. I can’t share on Stackblitz. But it is a simple standalone component. Its ChangeDetectionStrategy is onPush and implemented from AfterContentInit, OnInit, OnDestroy.

@JoostK I can confirm the fix has resolved the issue for me.

16.2.6 has been released, could people try updating to see if the issues have been resolved?

JoostK on Sep 20, 2023

@roma2341 unfortunately we had a bug in Angular v16.2.4 impacting signals. This is fixed now in the main branch and the fix will be released this Wed as v16.2.6.

In the meantime you can downgrade to v16.2.3 to check if this is a bug impacting you, as it is impossible to confirm without a reproduction scenario. If you still see problems after downgrade to v16.2.3 / upgrade to v16.2.6 - please share a reproduction scenario in stackblitz - the information we’ve got so far is not enough to diagnose and fix the problem.

This will very likely be fixed by #51722, but a repro would help us validate.
