Hello everyone, I'm seeking advice regarding my glitching MacBook Pro. While working on an application earlier, the screen was functioning perfectly. However, after closing the laptop for a few minutes and reopening it, I noticed colorful horizontal lines appearing all over the screen. I want to highlight that I did not drop the laptop. This issue has arisen suddenly, and I'm unsure of the cause. I'm looking for possible solutions aside from a screen replacement, as this laptop is crucial for my academic endeavors, and I'm unable to afford such a costly repair. Any assistance would be greatly appreciated. Thank you.

what exact MacbBook Pro?
the basics shut down and restart.
If Intel mac you can Try resetting NVRAM/PRAM Reset NVRAM on your Mac - Apple Support
(hold to get at least three continuous rounds of the chimes when resting the NVRAM, no harm there)
M series Mac you can try A SafeBoot Use safe mode on your Mac - Apple Support will sort many anomalies
You can plug in an external monitor and compare your results, if it is your display the external comes staight from the GPU bypassing your display. Horizontal lines typically indicate a GPU issue— the Discreet GPU is the one that typically fails if yo have 2 GPU.
You may be able to force to the Integrated GPU only on Intel if you have two.
