App crashed in xcode 11.6

When I tried to build app in xcode, I got this exception and I have no idea where to look for a solution:
Exception NSException "data parameter is nil" 0x00006000014d7960.

And this is the code that's appear:

Code Block DISPATCH_NOESCAPE dispatch_block_t block){
	if (DISPATCH_EXPECT(*predicate, ~0l) != ~0l) {
		dispatch_once(predicate, block); //Exception in this line: Thread 2: Exception: "data parameter is nil"
	} else {
		dispatch_compiler_barrier();
	}
	DISPATCH_COMPILER_CAN_ASSUME(*predicate == ~0l);
}
