Latitude 5175 Bitlocker issue

Hello. Recently installing new BIOS .22 I have got somehow BSOD “CRITICAL_PROCES_DIED”. BIOS flashed successfully but on each time on start system requested Bitlocker code. So I switched Bitlocker off and decoded SSD. Now it works normally but I can’t switch Bitlocker back getting the message “internal error has occurred”. I’ve tried to clear TPM from BIOS but it doesn’t helps. SSD hardware test passed successfully.  

Do you have any suggestion how to fix the bug?

Thanks.
