Logic Pro CPU Core Distribution Issue

Hey! Long time logic user here, and I've had this question for a long time and never thought to reach out to the Logic forum about it, but I run pretty high track count sessions and have pretty consistent issues with maxing out my CPU. Super confusingly though, its only ever one core that gets maximized and the rest of them seem to be pretty under utilized. Logic seems dead-set on overloading this one core instead of distributing the computing power, and every time this singular core is maxed out my session goes into overload, de-synced samplerates, etc. So many issues caused because it seemingly wont let the other cores process lol. Is there any specific reason it does this? Is there potentially a work around to convince it to actually use my other cpu cores? I'm on an M2 Ultra Mac Studio as well, so I figured I would never run into system overload again after that purchase, but alas I'm confused. Any input would be appreciated!

Mac Studio, macOS 15.6
