Most likely the other application is registered as URL handler for tidal instead of strawberry.
Open a terminal and type:
xdg-mime query default x-scheme-handler/tidal
To find which application is registered for Tidal.
If it's another application you can temporary remove that desktop file (usually in /usr/share/applications/).
Also make sure that the desktop file for strawberry is correctly installed (org.strawberrymusicplayer.strawberry.desktop).
