Read the instructions.

I'm currently installing carpet in a new home in three bedrooms. The bathrooms are tile but the laundry room living room kitchen and hallways are all click together vinyl plank and all areas are connected.
The entryway, dining room, living room, kitchen are all one large area about 35x25 ft.
From the laundry room hallway down through the living room and continuing to the end of a short hallway leading to a bathroom is about 37 ft in total length.
The customer requested that the vinyl plank flooring butt up to the tile in the bathroom at the end of the hall. They didn't want a transition molding. (a transition molding would have allowed for expansion)
The installer did what they asked. He glued down the planks that butted to the tile to keep them from moving up and down .
The laminate plank flooring has probably been down for at least a month and the heat was not turned on before or during the installation of the laminate.
According to the manufacturer 55 to 85° is okay and no acclimation is needed. That means the flooring was installed within the manufacturers temperature limits.
They also said to leave a 5/16 in gap for expansion.
Okay here's where the problem comes in. I'm getting ready to install the carpet so I changed the heating system from 60° to 70°. By the end of the day, there is a noticeable hump forming in the short hallway where the laminate was butted to the tile.
Yesterday morning the hump in the floor was over 3/4 of an inch tall in a 4 or 5 foot span.
Here's a couple photos. The one with the tape measure was taken last night and the ones with the 2x4 were taken this morning.
When the instructions say to leave a 5/16 in gap around the perimeter, and specifically says not to glue the floor down......... I'm kind of sort of maybe guessing that they mean it.

I wonder if you would have eased the temp up a little at a time if it would have made a difference. Back when we had installers that cranked the heat to install carpet in a new build in the winter and forgot to turn the heat down. It was high over the weekend and one Monday all the drywall had cracked and the floors had squeeks everywhere. Installer got to replace all of it.

The heat should have been on 65 or more degrees back when the laminate flooring was installed and stayed that way. The home was started in February last year.
The laminate floor hump would have grown to the same height if I had raised the temperature 1° per day over 10 days.
The installer should have told them the heat needed to be on. At the time the material was installed the nighttime temperatures were in the 40s and the daytime temperatures near 60, and the installer said the heat was not on when he installed it.
I would have refused installing in a nanosecond.
