Mac OS Intel 64 -- Jellyfin Doesn't Show up After openint

[glassjar]

2018 macbook pro Intel i7 Sequoia.  Installed AMD64 DMG (Don't see an Intel option).  Moved to applications folder.  Click to open.  Nothing happens--ever.

Attempt to delete app.  Message stating--can't delete Jellyfin because it's open.  Doesn't appear on Force Quit list.  Only way to stop invisible process is restart laptop.

What am I doing wrong?  Mac doesn't have ARM Chip (M1-3).

Thanks.
