It looks like you are missing the challenge_timezone DB column. Can you run this:
./launcher enter app
su discourse -c 'cd /var/www/discourse && bundle exec rails runner "ActiveRecord::Base.connection.add_column(:daily_challenges, :challenge_timezone, :string, default: \"UTC\") unless ActiveRecord::Base.connection.column_exists?(:daily_challenges, :challenge_timezone)"'
That should add it. I will investigate why it didn’t get added and update files.
