The full bullet point mentioned in the Release Notes is:
Fixes the Toolbox -> Choose Items command when a non-English language is selected in Visual Studio.
The release notes do not suggest that they addressed the MAUI ToolBox issue you reported.
I'm closing this thread. Please do not post multiple threads on the same subject, and please post bug reports for Visual Studio tooling in the VS Feedback site per How to report a problem with Visual Studio and bug reports for MAUI in the MAUI repo at https://github.com/dotnet/maui.
