          I have downloaded the file Qualcomm_USB_Driver_v1.010065.1.zip from qcomdriver.com, extracted it and started Qualcomm USB Driver v1.0.10065.1.exe.
          The installation seemed to be successfull.
          In the Device Manager is still an exclamation mark, when pluging in the phone while in fastboot-mode.

          In Terminal "fastboot devices" brings no results.

            @frifo So that essentially rules out the driver. Unplug the device from the PC and reboot the device and your PC.

                        That means there is an issue with your drivers.

                          Along with the phone a driver OnePlus_USB_Drivers_Setup was delivered. I have also tested this driver. But it doesn't work.

                          Is it possible, the Windows 11 is the problem and it has to be Windows 10?

                            Now I could unlock the bootloader.
                            Windows 11 Pro didn't work.

                            But Linux Mint 21.3 Cinnamon works:
                            Open Terminal.
                            adb devices
                            adb reboot bootloader
                            fastboot oem unlock (works)

                            ubport installer worked.

                            Thank you for your help!
