Midi stopped working with iOS 15.4

Is anyone else having any issues with midi programs not working via camera connection kits to their music workstations via usb connected to the keyboard? My Yamaha M08 worked perfectly until iOS 15.4. All of my midi apps freeze, then crash with this update.

iPad, iPadOS 15

This is weird. All my devices with 15.4.1 stoped working after update. Now I’m using a din cable and it works back on all devices.


These are the possibilities I tried here.

Cable

USB-B to USB-A with Lighting Camera Adapter or USB-B to Lightning (Agvee)

Devices

iPhone 13, iPhone 8 or iPad Air 2

iOS 15.3.1 work.

After iOS 15.4 don’t work.


Cable

USB-B to USB-A with USB-C Camera Adapter or USB-B to USB-C (Ugreen)

Device

iPad Air 4

iOS 15.3.1 works

After iOS 15.4 doesn't work.


MIDI DIN to USB-A with USB-C Camera Adapter or lightning Camera Adapter

All devices are working. Tried on iPhone 8, 12, iPad Air 2, 3 and 4. All with 15.4.1.


I'm using a DOREMiDi Brand cable. This is the only way I found to use SimplyPiano for while, at least, until Apple fix this problem.
