I am unable to replicate this error, but I do have a hypothesis (but is only applicable to flask).

Our isNonEvmChainId does not check all non-evm chainIDs

metamask-mobile/app/components/Views/Settings/NetworksSettings/NetworkSettings/CustomNetworkView/CustomNetwork.tsx

Lines 52 to 57 in 2d6f6ed

	if (
	isNonEvmChainId(networkConfiguration.chainId) ||
	isNonEvmChainId(savedNetwork.chainId)
	) {
	return false;
	}

It only checks mainnet sol and btc
https://github.com/MetaMask/metamask-mobile/blob/release/7.46.0/app/core/Multichain/utils.ts#L103-L105

So devnets are not included, and can potentially cause this crash.
