I have a similar problem, after the update it ran fine for a while, then it crashed and after every login crashed again. I turned it fully of and on again, and it ran, but without WiFi, audio and more, and after accidentally turning off mobile data, I couldn’t turn that on again. I did a full reset to at least get mobile data running again.
Adb logs revealed, that there are files missing for the WiFi driver, so the service can’t run.
I am just going to reinstall the OS this weekend to hopefully fix it
