Problem with the activation of the store with shopware 6.4.20

already weeks I am screening the Internet for a solution to this problem.
I have installed shopware 6.4.20.2 locally and i want to install the shopware store but always falling on this error: "Plugin extraction failed. Error: Detected invalid file/directory SwagExtensionStore/CHANGELOG_de-DE.md in the plugin zip: SwagExtensionStore/.gitignore"

Here is the complete content of my log file:
[2023-06-15T04:30:34.243981+00:00] request.CRITICAL: Uncaught PHP Exception Shopware\Core\Framework\Plugin\Exception\PluginExtractionException: "Plugin extraction failed. Error: Detected invalid file/directory SwagExtensionStore/CHANGELOG_de-DE.md in the plugin zip: SwagExtensionStore/.gitignore" at C:\wamp64\www\newshop\vendor\shopware\core\Framework\Plugin\PluginExtractor.php line 109 {"exception":"[object] (Shopware\Core\Framework\Plugin\Exception\PluginExtractionException(code: 0): Plugin extraction failed.

Can someone show me how to address this issue?
thanks in advance

I tried reinstalling previous stable versions but still having the same problem...

It's an issue with the directory separators of Windows (\ vs /). This should get fixed eventually, as the intend is to offer maximum compatibility, but issues can't be fully ruled out. If you have to stick with wamp you could momentarily change this line to replace \DIRECTORY_SEPARATOR with '/'. Ideally however you should use a proper environment like Dockware to be on the safe side.
