Bug Very high build time for ios after upgrade

Hi, after upgrading from unity 2020.3.35f1 to 2020.3.41f1, the build time for ios got 4x+ slower on cloud build.
This happens in all my projects, larger builds fail because of 24h timeout, other developers have reported the same.
All times have an absurd increase:
