Hello! We seem to be having the same issue. After our reply, it's been over 24 hours and we have not received an approval or a reply. We have a critical bug fix that is now impacting our App Store reviews.

Toolbaritem applies the glass effect so there is no need to add .glassEffect. This is the reason you are seeing an additional background. See source code here: https://developer.apple.com/documentation/swiftui/landmarks-refining-the-system-provided-glass-effect-in-toolbars

Thank you!

This is helpful! Thank you!

Any update on this? I am seeing similar crash reports.
