Cannot run app on Simulator (RCTSRWebSocket assert failed)

Description

I am unable to run our app on the iOS Simulator, as it crashes on startup with an assertion failed:

Assertion failed: ([scheme isEqualToString:@"ws"] || [scheme isEqualToString:@"http"] || [scheme isEqualToString:@"wss"] || [scheme isEqualToString:@"https"]), function -[RCTSRWebSocket _RCTSR_commonInit], file /Users/oscargotting/ntwrk/ntwrk-mobile/node_modules/react-native/Libraries/WebSocket/RCTSRWebSocket.m, line 283.

The scheme seems to be "file" and it doesn't like it

NOTE: I recently moved to an Apple Silicon environment, I have no idea if this may be related.
