Thanks @DTS Engineer I've submitted new FB22576068 where it looks like a lot of network extensions have been broken, including ours This is on 26.5b3

@DTS Engineer Thank you. As of now the 25F5053d is not yet available, but will keep you updated after testing that one. FWIW - 23F5043g did not fix the issue

@WangZiYuan I submitted FB19734992 which has the same symptoms as you do. It first appeared in 15.6, and yes, as you mentioned much better in 26.2/3/4, but not fixed yet. It is a serious problem and can only be fixed by: Reboot Removing every System Extensions (which is not always feasible)

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
