Hi Viktoria,
I'm Dyari. Thanks for reaching out. I will be happy to assist you in this regard.
To fix this issue kindly try the steps below:
1-Try to use another keyboard if available and check if the issue still persists or not. If the issue still persists, it means the issue is software related and it is best to Update its driver from Device Manager.
If it did not fix the issue, uninstall the keyboard driver completely and download then install the latest driver from the manufacturer's website.
2-Change the keyboard layout and check whether the issue still persists or not:
