Wake from Sleep not working

Since updating my SSD and RAM in my computer with a fresh install of Windows 11 (twice, now) I am having an issue with slower bootups and also, a non-functional sleep or hybrid mode.

The SSD and the RAM are checking out with regards to integrity checks repeatedly, I've also run SFC and so forth command prompts to try and fix the issue as well as memory checks on startup, no issue.

The issue I'm told by Microsoft agents is likely to be the insider preview build I'm on? Can someone help.
