All new builds from TestFlight Suddenly started crashing on launch and with no Crash Logs on Crashlytics

Question

Getting a crash on launch since the night of 8th Dec 2021 for all processed builds from TestFlight. Also when run locally on the device, build runs without any crash for both release/develop schemes.

Only devices using iOS version 15 were working fine without any crash issue.

When installed from TestFlight on devices using iOS13 and iOS14 versions, this issue can be reproduced.

Exception Type: EXC_CRASH (SIGABRT)
Exception Note:
EXC_CORPSE_NOTIFY
Termination Reason: DYLD 1 Library missing
Library not loaded: @rpath/libswift_concurrency.dylib
"/usr/lib/libswift_Concurrency.dylib' (no such file)
(terminated at launch; ignore backtrace)
(no such file)

Also, an email was received regarding distribution on TestFlight: ITMS-90863: Apple silicon Macs support issue.

For which, I had disabled that already from Pricing and Availability -> and Unchecked Make this app available . But Still, the same crash issue was observerd.

Finally, Issue got resolved after installing XCode 13.2 RC , and Distributing a new build from this XCode version solves the issue.

Hope it will also help other people who might be facing the same issue.
