Why didn't my gf's feelings translate in person but mine did?

I'm going through a tough time and could really use some outside perspectives. My girlfriend and I had an amazing emotional connection when we were long-distance. She has been my rock through some very hard times. She even moved to my country recently to start a life here, and we were both so excited.

But now that we've met in person a couple of times, she's told me she's not feeling romantically or sexually attracted to anything right now, and failing to feel it with me. The thing is, I do feel it. In person, everything felt even more right for me. I'm very sure about her, but she says she's unsure and that she feels "on edge" and stressed because of all the changes in her life (new country, school, family pressures).

She says she finds me attractive, she's confident she still loves me, but she's concerned her body and emotions aren't responding in the way they used to. It's hard to hear because she used to be so sure about me (she even initiated our sexual relationship when we were long-distance). Now, she says she's questioning if we'll ever work romantically.

Some context:
-She comes from a strict, repressive culture, so although she has had an in person relationship in her country before, this was a big step for her. -She's also under a lot of stress adjusting to her new environment and daily life.
-She felt so strongly about me during the long-distance phase that I'm wondering if she only idealized me, and now the reality of being together is different from her mental image.

But I still don't know why her feelings translate in person when mine did (and neither does she). I know chemistry and connection can be complicated, but I'm struggling with feeling blindsided and hurt. It makes sense for stress to dampen feelings but not remove them completely so it feels like there is something deeper going on.

Is this just stress on her part? Could it really just be a "wrong time" thing? Or does this mean we're fundamentally incompatible? Should I give her more time to settle in and see if her feelings come back, or should I move on and look for someone who's all in for me from the start?

Thanks for any advice or insight you can share. I'm really struggling to make sense of all this.
