I can confirm the hotspot problem on my Fairphone 3 with 1.0-q-20220622198553-dev-FP3.
Additionally, a network reset doesn’t help.
Switched the slot to go back to the previous 1.0-q-20220527189323-dev-FP3 as mentioned in the GitLab issue and above … OS booted successfully, problem was (before trying the new update) and is (after going back from the new update) not present for me on 1.0-q-20220527189323-dev-FP3, hotspot works.
