Since buying and installing Battlefield 6,, Steam has been behaving oddly.
I can launch the desktop client but it takes a very long time to open. Once opened, only my library is loaded. The store,, community, profile, etc,, show an error -7 (connection issue). I can play all my installed games but can't do anything else.
I have done some investigation. The only change is enabling the secure boot. This allows BF6 to run but won't allow Steam to load anything other than my library.
I have switched off secure boot and now BF6 won't run but Steam is back to normal, loading the store and everything else. It also loads the client really quickly.
Can you suggest anything that may help? I have cleared cache,, signed out and back in, restarted my computer 10 times, changed from wired to wifi and back again,, changed network twice.

Any help would be very much appreciated
