Ukrainian with permit C and expiring passport

Hey,

Ukrainian, working here since 10 years (8 on B permit), ukrainian passport expires in 2025. It's impossible to renew passport (all consular services denied without any written confirmation, must travel to Ukraine, it's impossible for men, to get out of Ukraine legally currently)

How not to get deported? Because that's what Migrationsamt suggests would happen. Switzerland is my center of life, and I have 0 ties with Ukraine, not living there since 15 years.

Does anyone know people with similar cases?

Any tips would be appreciated.
