Hi,

We are seeing a crashing bug with relatively high frequency in our app related to EAAccessory and the OS appearing to trigger an assertion when a run loop source is signalled.

The crashes occur in a variety of device types, but all crashes are on iOS 14, not earlier OS versions.

If anyone has some tips for how I might go about debugging this, I'd appreciate it. Our app interfaces with MFI peripherals from several vendors, so much of the EAAccessory related code we have is from closed-source third party SDKs.
