Got some output from chrome:
Audit usage of navigator.userAgent, navigator.appVersion, and navigator.platform
A page or script is accessing at least one of navigator.userAgent, navigator.appVersion, and navigator.platform. Starting in Chrome 101, the amount of information available in the User Agent string will be reduced.
To fix this issue, replace the usage of navigator.userAgent, navigator.appVersion, and navigator.platform with feature detection, progressive enhancement, or migrate to navigator.userAgentData.
Note that for performance reasons, only the first access to one of the properties is shown.

But got the answer already "first Alpha"
Good practice is to add comment to content f.ex. "Network - Not ready yet" or something similar to prevent stupid questions like mine
