WhichBrowser\Analyser\Header\Useragent class uses dynamic variables: $data and $options.
Requires to declare them in class or in constructor method

WordPress 6.4.3
PHP 8.2

WhichBrowser is not maintained anymore therefore I will replace it with a different solution

@duracelltomi What is your plan forward with this? We are getting spammed with this error in our logs :/

PHP: 8.3
WordPress: 6.6.2
GTM4WP: 1.20.2

I postponed replacing WhichBrowser as it is quite a big change in the plugin code.
If you do not need browser/os/device data in your tracking, you can simply disable those plugin features.
