fSpy Window Not Appearing on macOS Tahoe

[HOVO3D]

Hi, I’m having an issue with fSpy on macOS.

The app opens, but only the name appears in the top-left menu bar. The actual window does not appear, even when I click “Open Image”.

I’m using a Mac Pro 7,1 (Intel) with the latest macOS Tahoe version.

I already tried restarting the app and reopening it, but the issue remains.

Do you know how to fix this or if there is a compatibility issue with the latest macOS version?

Thank you.
