I have the same problem. For mine I noticed if I wake the computer before the ssd wakes up I get the error. If I bump the mouse before opening my laptop it wakes up the ssd and then I open my Mac. I forgot to do that this afternoon though, and I forgot how I fixed it last time. Does anyone have a solution for this? I need to access documents on this drive for a class and I cannot for a simple silly reason. Th ssd never unmounted it just went to sleep with the computer.
So frustrating.
