All chat apps crash abruptly during video calls.

On my iPhone 13 Pro, video calls on WhatsApp, FaceTime & Skype would cause the app to crash abruptly. Siri would show up along with the volume slider. Contacted Apple Support multiple times; they asked me to Restore my phone. The solutions provided did not work. I figured out that the 3.5mm to lightning Apple Adapter that I was using to connect my wired earphones was defective. I am now using a similar but new adapter & the issue is resolved. I couldn’t find where to post this resolution & hence this post. I have informed the Apple Support via phone, but I doubt that they will post this resolution online. Hope it is helpful to others facing a similar situation.
