@toshanmugaraj That is a different issue seen when using Xcode 14 instead of 13 and was fixed by #6728.

sorry to say that my Element still crash even after i update it to 1.9.7，should i offer newer crash logs or more details？

[pixlwave]

Ideally we need more details. From the crash logs alone we don't have enough information to reproduce the problem. Just to double check: Assuming you have another client or the key to restore your keys, have you tried uninstalling and reinstalling the app? If that didn't work, or you can't as you would lose your keys, it seems as though a specific room is causing the crash, so if you're able to dig in deeper to find out that room's ID and then let us know more information about it, it might help us to dig deeper.

How could I offer more details or find the “specific room” which is causing the crash，because my Element-Web and Element-Windows seems working normally，only Element-iOS will crash.

just FYI, I have the same problem on one of my accoutns, one of my iphones and clearly I think this is because too much chans are subscribed or maybe because of the old chans which actually redirect to new chans. And how would you like to transfer the logs? Because it's not like we have a pop afterwards to actually be able to send logs liek we can on other apps on iOS....

ios 16.0.3 element up to date from the app store of course and this is happenning for several iterations of element.
