I have a solution
5 eyes should combine resources- and get more resources from their governments (they like plans that give them more money, don't they?)- to work together on a very, very big computer to crack encryption.
Starting from the lower end old flawed encryption schemes, working through known implementation errors, and following this process. Keep a list of known 'weak spots' where things are decrypted or where useful metadata can be harvested.
Keep doing that until they're left with no choice other than to break out the Big Gun and brute force it.
So we chuck money at them to chuck at crypto research, quantum computers, massive supercomputing and GPU based parallel processing with the aim of becoming able to crack pretty much any encryption they come across.
The result? They're happy as they've got stacks more funding and legal permission to break any encryption by a weakness in it- whether that's a small key, an implementation flaw, or suchlike.
And everyone else wins as they pour money into research helping quantum computing, graphics processing and other fields which benefit the rest of us. Plus, if they never succeed the rest of us remain secure.
