Crash Related to Keychain/Auth Data

[kevinyou77]

Describe the bug
Hi team, we’ve been receiving some crashes within the WalletConnectV2 SDK for iOS. Was not able to reproduce these crashes though. Asking here so maybe you guys can take a look on what the root cause is, but judging at the crash logs, it happens when the SDK is initializing. The crash only happens when we've upgraded to 1.9.8
Note that we’ve changed the endpoints in the SDK to have .org extension since .com endpoints have issues in some countries.
Do let me know if you guys need anything, thanks!

SDK Version

• Client: 1.9.8
