Currently using keyboard in Finnish and nordic QWERTY layout. @ sign that used to work with altgr+2 or ctrl+alt+2 suddenly stopped working couple days ago. Whenever switching between any nordic layouts @ sign won't work but if I select language to english USA and/or USA QWERTY layout @ sign works perfectly well with shift+2. Other combinations with AltGR or CTRL+ALT work perfectly well in nordic and usa layouts. On-screen keyboard won't place @ sign aswell if I'm in nordic or finnish layout. Keyboard is Corsair and checked from iCue that layout is Nordic aswell and there I can see that altgr+2 is responsive so nothing seems to be broken. All the driver updates and Windows 11 pro updates are done. Only thing left is reinstalling whole windows.
Every other guide just tell to switch from layout to another but since I'm using ÄÖÅ letters I'd rather stay in finnish layout.
