Given what you have said about that overwhelming feeling of the lack of guidance, I am very tempted to categorize it as a rather common problem of a poor fit in terms of personality.
You see, advisors exist on a certain spectrum of how much independence they want or expect from a student. This is a subject to a whole lot of influences ranging from the lab needs at a specific moment in time to personality quirks. Few researchers are good managers. A good manager would be able to be very flexible about their approach and treating the student the way that is the most efficient for that student. For some advisors it does comes naturally, for others it is a lot of effort. The latter is more common by far.
Students are also very different: some need at least an initial spark to get going, others prefer something more free-form. Some are more productive with fixed office hours and have a hard time working from home, others detest having more external control over them than absolutely necessary to get the job done. The list goes on.
This variety in approaches can (and often does) culminate in complaints from both sides. Either the student is unhappy with being micromanaged or the advisor does not get how (perceived) micromanaging could make someone happy and fulfilled. Yours seems to be the latter case - you want more input and the advisor might be thinking that approach is a dead end.
The above is reading way too much into your situation and probably being overly dramatic, but I reckon this is the gist of it - the advisor wants you to be more independent than you are ready to be. That is not necessarily a bad thing, some professional growth opportunities are lurking nearby, but you do seem to have communication issues.
You do need solid footing to begin with, and your advisor suggests finding something that excites you. I wholeheartedly agree. Given that you struggle with soul-searching and navigating this new field, find something that does work for you and express that in communication. Even with all the experience and wisdom in the world, a closed stance of "I do not like this and that too much" is not a lot to act or advise upon. Exploring something you liked in another field, possibly finding connections or describing what was so great about these things would be a great start. You have to confide in your advisor a little more about your desired academic path... Or find a new one, it would seem. Alternatively, it is possible to finish your MSc a bit miserably and move on to something else, but as long as there are other options, explore them first.
TL;DR: Find something actionable for your advisor - at very least a detailed example of an input that would work for you and a description of what exactly is lacking from their existing guidance. You are increasingly pressed for time - it is prudent to make more open moves. If you are in the midst of a slow boiling conflict, it is better to bring it up now and buy yourself some time to navigate it than to slowly suffocate and still have that conflict shortly before the thesis deadline.
