React Native - iOS crashes when Flipper is upgraded above 0.69

See original GitHub issue

🐛 Bug Report

After upgrading Flipper above version 0.69 in my React Native (0.64rc3) application, it keeps randomly crashing every few seconds. I believe it’s related to an upgrade to FlipperRSocket.

To Reproduce

Upgrade Flipper above 0.69 in a React Native application
Launch the application in an iOS simulator

Environment

iOS simulator, I’ve tried with iPhone 11 14 and iPhone 7 13.5, both crash.

Date/Time: 2021-02-17 15:45:46.991 +0000 OS Version: macOS 11.2.1 (20D74) Report Version: 12 Bridge OS Version: 5.2 (18P4346)

For now the only workaround I’ve found is to revert back to 0.69. Let me know if I can provide any additional information.
