Invariant Violation: Calling synchronous methods on native modules is not supported in Chrome.

[mfbx9da4]

I've been trying to get started with a fresh project and I've hit multiple stumbling blocks. My fresh project is a fork of the recommended react native typescript template.

1. Had to enable use_frameworks!.
2. Had to disable flipper as was recommended, presumably because flipper depended on use_frameworks being disabled.
3. Had to tweak some other packages to be compatible with use_frameworks!. In my case I had to enable $RNFirebaseAsStaticFramework = true for firebase.
4. When using react-native@0.66, I had to do a force install because the packages because virgil packages don not declare themselves as compatible with react@17 npm i @virgilsecurity/e3kit-native @virgilsecurity/key-storage-rn react-native-keychain react-native-virgil-crypto --force. Also had to install npm i @react-native-async-storage/async-storage instead of the recommended @react-native-community/async-storage

After all this it "works" provided debugging is not enabled. If I enable remote debugging I get the following error when using virgil APIs

Invariant Violation: Calling synchronous methods on native modules is not supported in Chrome.

This error is present with react-native@0.62 and react-native@0.66 configurations.

I'm also experiencing this with 0.62

looking through the source the issue is that the library always exports with RCT_EXPORT_BLOCKING_SYNCHRONOUS_METHOD. So this error is guaranteed to happen... Do I have to fork the library and re-export everything with RCT_EXPORT_METHOD?
