Unable to start Hearthstone -- iMac 2020

For problems installing or patching Hearthstone, or crashing during game play while using a 2020 iMac.

I’m seeing HS:CT;NetCacheProfileNotices=0;NetCacheDecks=0;NetCacheCollection=0 in the upper right hand corner of my screen.

In the center I am seeing the following message from Hearthstone:
Your game timed out as it was requesting data from the Hearthstone utility service. Please relaunch hearthstone to reconnect.

I have tried to reinstall Bnet and hearthstone with no resolution.

I’ve tried to clear out all caches I could find and once again reinstalled. No luck… any help from blizzard?
