It will be hard to give you definitive answer without knowing exactly what your step-by step process was, and even then, it may come down to simply guessing.
Unfortunately with finishing, sometimes sh*t happens (weird, inexplicable sh*t).
If it was from a rattle can, it could have been a bad batch. You never know.
Last year I used Dulux Duramax base coat then clear coated with their Duramx 2k (allegedly completely compatible per their support) and it WRINKLED like buggery! Also worth noting I followed their instructions to the letter. I won't touch their stuff with a barge pole now.
As Sonic said, a clearer close up pic would be more helpful. Hopefully the BYOG brains trust can offer some insight & help.
Me, I'd just be stripping it and starting over. Sometimes it's all you can do...
