I Found The Solution : from my experience
----------------------------------------------------------
1 - Bootcamp can't finish install windows successfully on MacBook Pro 16" 32GB Ram, 2TB SSD , Radeon 5500 8GB
2 - Run Bootcamp and download Windows Support Software
3 - Create about 8GB xFAT Partition , Copy windows installation then copy Downloaded Windows Support Software And Create Windows Partition With size you like > 100 GB. xFAT or FAT32
4 - Restart With Holding Option Key and choose Windows Partition,
5 - When Windows Setup Starts it will ask about driver ( Windows can't see 2TB SSD )
6 - Click browse the goto windows support folder and locate AppleSSD.inf -> choose it , click ok
7 - Windows will install driver then all partitions show up
8 - that's it , now select your Windows Partition and continue setup as you know
i hope this will help any one have the same configuration or the same issue
