I'm writing this in a more easy way so your google translate will work better i hope.
You never answer the questions. Please answer us:
Do you own the dongle for the Tekken 7 game?
Do you replace any hardware item in the PC before it stopped working? Maybe you change the CPU? VGA? Boot with no CPU/HDD by accident?
If you replace HDD/VGA/CPU, then TPM protection kicks in, and will lock the system like you have now.
Bitlocker key is based on the HDD/VGA/CPU/MAINBOARD combination. If anything changes, it will change key -> hdd cannot decrypt -> error.
First check all the cables to HDD, push VGA into socket, all of those, check it.
If the HDD is defect, you can never use this combination now.
Unless you get all NAMCO provided stuff, Dongle, HDD, VGA all must be from ES system.. not random VGA 1060 or whatever.
So you better read the other topic:

Short steps:
Disable TPM. Your ES3 becomes a normal PC with some extra hardware. You can boot Windows install from HDD. Use any HDD.
Use Google to find non-encrypted cracked dumps. Write the dump to a new HDD.
