[MatthewPierson]

This is likely an issue with your dualboot, not PyBoot

[wqhqq1]

but i do not use any dualboot. just boot original system

[MatthewPierson]

Ah my apologies, I mixed this up with another issue! Did you downgrade to this version from another one?

[wqhqq1]

i use ota upgrade to this version

[wqhqq1]

now i upgrade to 13.5，i will try that again later

[wqhqq1]

also panic on 13.5(ipad mini4),and i will upload logs later
