Thanks @DTS Engineer, @kithrup I've added a new Sysdiagnose to the ticket after re-testing with 26.3 Beta also.

@DTS Engineer Do you have any update on this one? FB19631435 FB19734992 Curious if you have any way or hint on how to resolve this? As mentioned it seems to have been introduced in 15.6, but hasn't been fixed in 26.2 either
