Hi Johann,
I'm Christine, a Windows user like you. I can see here that your screen turned to color green. Usually this kind of issue occurs due to driver issue or hardware itself. No worries, I'll do my best to help you.
Please send the make and model of your device. (Please press Windows key + R and type msinfo32 and hit enter, look for system model)
Update or Roll back the Display driver
Please press the Windows key + X
Then click Device manager
Kindly expand the Display Adapters
Right click and choose "Update Driver"
Select "Search automatically for drivers"
If the issue persists Choose "Browse my computer for driver" instead
and click " Let me pick from a list of available drivers on my computer"
Choose the older version.
Please restart and check if the issue persists
Please let me know the result. I'll be happy to assist you all the way until it's resolved.
Thank you,
Christine L
