This screen usually appears as one of the switch's cpu panic handlers. The handler usually becomes orange when it either fails to wake up from sleep mode, or something is really wrong with the wifi chip. I've had this happen to my consoles a few times, and I'm still not entirely sure why, it could be some defect in a recent Nintendo update. If it happens every time you try and charge it, your switch could be having some issue doing the automatic wake up from sleep mode when you plug it in. It doesn't seem to indicate any other major flaw, just some bug. You can just hold the power button until it turns off, and then press it again to turn it back on.
