Exception occurred when dragging file from Explorer

[Timwi]

I dragged this TTF file from Windows Explorer onto Character Map UWP.

The application called an interface that was marshalled for a different thread.

The font URI specified is not a valid application URI that can be opened by StorageFile.GetFileFromApplicationUriAsync.

Thanks for the report! You seem to be running quite an old version, the 2025.1.2.0 version is the latest in the store and should have a fix for this (it is an issue caused by a Windows Update).

If you can, do any updates show for you in the Microsoft Store?
