The wilting is caused by the heat, and it may bounce back soon from part of that, not all. I see it's been 22 hrs since you posted, so this may look a little better already from just chilling overnight. However specific damage to the leaf surface is hard to tell in the photo, but you're likely to have some. It doesn't get revived or repaired, you'll need to grow new leaves to replace those. Often the full extent of the sunburn damage isn't fully apparent for days. Usually it starts as whitish areas that quickly turn yellow then crispy brown.

For now, just take care of it the best you can as for a normal healthy plant. I notice some of your leaves are larger than usual for Monstera deliciosa before getting their splits. This usually means not enough light. If you can increase the light in any way, it would help in recovery. Moving closer to a window is the usual way, but perhaps in way that will give it direct sun only before 11 or after 3 pm. I'm sure you are already familiar with the dangers of sunburn! Another way is to add a floor lamp or light fixture above it for some extra supplemental light. Good growing!

Hello same thing happened to my plant today. Can you pls give me an update to yours

Whenever you move a plant from indoors to outdoors you need to give it a gradual hardening off period. When you first put it outside put it in the shade and leave it there for a few days. Then move it someplace where it will get dappled shade and leave it there for a few days. Then move it to where it gets a little more sun. So on and so forth.

FYI most houseplants are generally not full sun plants and will get pretty toasted if left in full blazing sun for several hours per day. This can vary depending on your location. The sun's rays are more intense the lower your latitude. For example, 5 hours of direct sun in Michigan or Washington is very different from 5 hours of direct sun in Missouri or Tennessee. Plants can take more sun in Washington or Michigan because they're higher latitude states.
