Hello,
Welcome to post in the Microsoft Community Forum.
It seems to be a known problem with Windows 10 and 11 where the text color in some applications becomes unreadable due to the color scheme settings.
If you're using any third-party software for desktop customization, it might be causing the issue. You can try closing the third-party app.
Here are some examples to consider:
Unreadable font ... White on White Background and Text - Microsoft Community
mouse over texte unreadable - White on White - Microsoft Community
If the problem persists, it's best to report it directly to Microsoft through its feedback center app. To learn more, see Send feedback to Microsoft with the Feedback Hub app.
Microsoft will continue to evaluate and improve its products to provide the best possible user experience.
Regards.
