host win 10, iso x 86 in VB installs fine, but install iso x 64 does not reach the prompt window, although there is no such freeze on another computer. In safe mode, it reaches drive.sys and stops. What could be the problem?

Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

Thanks for the answer, the log is in the attached file.

You have Hyper-v enabled. Please read the last post of FAQ: I have a 64bit host, but can't install 64bit guests. I suggest that you go directly to the "bcdedit" instruction.

I suggest that you also give 2 cores to the VM, set graphics RAM to 128MB, and install the host Extension Pack.

Thanks for the answer, thanks for the link, but Hyper-v has been disabled. But I realized that I need to check all the windows 10 components again. After turning off the Windows Sandbox, the installation was successful.

PS: sorry for the english spelling.

Yes, sandbox is another one which causes trouble - it runs in a virtual environment, like WSL2 etc etc.

If that was true then the quoted line from the log would not have been present.

You need to understand the difference between the Hyper-v "manager" which creates VMs and the underlying Hyper-v "engine", which the log refers to as NEM. Originally the two things were one (more or less), but these days a lot of Windows 10 security features implicitly enable the underlying engine. This is also what the FAQ told you.
