In the snippet of configuration you posted, you have no passphrase set (maybe you edited it out? Or it the default "sensitive switch" that doesn't display it?)
Usually (but not necessarily) a profile is created in:
/interface wifi configuration
settings go there and you apply the named configuration to the interface(s).
The passphrase should show in
/interface wifi security
Check that you have it.
Anything in log? (when you try scan and then connect)
Try replicating this set of configuration:
Try with just one wifi interface at first, either the 2.4 GHz or the 5 GHz one (BTW you only have wifi2 in bridge, if this is intended, fine).
