Description

After version 2.18.5, I have started getting issue

./node_modules/@hethers/wallet/node_modules/@hashgraph/sdk/src/PrngTransaction.js 109:43
Module parse failed: Unexpected token (109:43)
File was processed with these loaders:
 * ./node_modules/react-scripts/node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
|     const body = /** @type {HashgraphProto.proto.ITransactionBody} */
|     bodies[0];
>     const transactionRange = body.utilPrng?.range;
|     return Transaction._fromProtobufTransactions(new PrngTransaction({
|       range: transactionRange

I think due to ?. Javascript is throwing this error while starting app. When I looked into it more, it looks like introduced in this PR #1302
