How do you fix a red cast in the laptop display?

Since today my laptop has a red cast in the display, although it is new (I got it 10 days ago). I'm very sure that this is a software bug, since the red tinge only appears some time after you switch on the laptop and it also disappears for a few milliseconds, for example when you press the on / off button on the Bluetooth or a page in Microsoft Edge is loading. I know this is unlikely, but could it be because of the Lenovo ThinkPad pen pro that came today or the Lenovo Pen Settings app?

About my laptop: I have the Lenovo IdeaPad C340 laptop with a Ryzen 3 3200u CPU in Windows 10 S mode

I would be very grateful if you could help me. MfG, alexzz990

Check whether "night mode" is activated for you and deactivate it.

You can change the "Windows 10 S mode" once to normal mode. Then you are not limited to the Windows Store when installing programs: https://support.microsoft.com/...s-mode-faq

Night mode is already switched off.
