I have an Opel Crossland 2019. I tried to install the update via USB via Opel software. Due to an error now a blue screen. Tried several USB sticks. But it keeps showing software error. Does anyone have any software that works for me? I think I also need a license key. 21.08.90.52_NAC-r0 or 21.08.87.32_NAC-r1

For those who encounter problems (blue screen) on Wave 2 after the update with v21.08.90.52-r0 (The certificate has expired on 2024/11/03) :
Prepare a USB key with a valid map update, such as V27 (Any version, it will not be necessary to install i.). Plug the USB key into your vehicle, the screen will restart and work properly.
