Installed Ventura on early 2015, problem with nvme SSD only when installed internally.

(Tldr; crucial p3 SSD only boots via USB in enclosed case, not when internal.) Hello, I installed Ventura on my early 2015 MacBook pro and it installed/patched no problem. Now I'm trying to switch out my old Mac SSD with a Crucial P3 plus, bought the adapter as well as an external case. Used disk utility to clone to new SSD. And when the new SSD is external, it boots the OS no problem. Only when I swap out the original SSD for this one internally, I'm met with the " folder/? " . When I enter disk utility sometimes it'll show as device locked and sometimes it doesn't show at all. Tried to partition a small amount as FAT but nothing. Is this possible? Or if not, any way to make Monterey recognize nvmes?Any help is much appreciated!
