Trying to give my GoPro 11 Black a solid run over a weekend and I've been having frequent power on issues with it.

With my brand new GoPro 11 Black, I've been having several issues with powering it on, even with fully charged batteries. Here's the thing, I'm using 3rd party batteries which I have previously used with my Go Pro 9 Black and that camera performed perfectly with no issues. Are the batteries possibly causing issues, or is there something else wrong? I'm wondering if I shouldn't be using the same batteries even though they fit. I'm also using some SanDisk Ultra Micro SD cards, and they aren't recommended speed for the 11. Is there a chance these may be an issue as well? I just would like to be able to use this camera with no issues, and if anyone has encountered these same ones, and was able to overcome them, I'd like to know what was done to resolve them.
