@WAslayer is spot on.
The laminate expand and contract as the moisture in the air changes.
Had same issue when we moved in, floor started lifting up at one of the points we walked the most.
You will have to rip off the side skirts and hope you can figure out which end they finished the install. I lifted it up on the wrong end /sigh
Anyways, then when you can see where the strips are pushing against the wall, you need to uninstall back to that point (aka remove the strips) and then then cut off small pieces to shorten the strips. You want about at least 0.5cm gap between the wall and where the laminate strips end.
When done, put everything back and use the side skirts to hide the gaps.
Annoying as hell depending on how much of the floor you need to uninstall.
