import { generateChildLogger, generatePlatformLogger, getDefaultLoggerOptions } from '@walletconnect/logger';
^^^^^^^^^^^^^^^^^^^
SyntaxError: Named export 'generateChildLogger' not found. The requested module '@walletconnect/logger' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@walletconnect/logger';
const { generateChildLogger, generatePlatformLogger, getDefaultLoggerOptions } = pkg;

downgraded the reown packages version to 1.7.9 and it's working now

+1 to this, why is this breaking at the later 1.8.XX versions?
