Pink screen freeze

Good evening,
I need help with a problem on my switch.... After an update, we restarted the console and a pink screen appeared. Since then, nothing works... While searching online, we attempted multiple manipulations.... disconnecting the console, putting it back on the dock but the screen remains pink... it doesn't work on TV or in handheld mode. We also tried to reset (recovery) by pressing the volume and power buttons simultaneously, but nothing works. It turns off and when we turn it back on, the screen stays stuck pink!! Does anyone have a solution? Knowing that the console is less than a year old and has had no bugs until today...
Thank you!
