I’m sorry to say you shouldn’t be surprised.
You already had notice from the Czech authorities that you did not qualify for a Class 1.
Its a little difficult for me to believe that you never ever in your life suspected a color deficiency.
You basically shopped around till you found a Dr that failed you on one and passed you in the other one.
You could have suspected the license transfer would be a problem.
In any case that’s all behind you now.
Simulator instructor, ground instructor, cabin crew, Dispatch, airport operations are all options for you.
Maybe fly and teach aerobatics on the side?
Unfortunately this happens every day that somebody looses their medical.
This is just an afterthought and shouldn’t be considered a recommendation:
You may just barely qualify for a FAA Medical First Class and transfer over all your licenses and find a way that you can fly US registered aircraft without actually working in the US as a greencard or work permit are out of the question.
Except for the FAA…..medicals in other parts of the world can be very, very strict.
China is (in)famous for their astronaut like physicals and many countries are close behind.
