Hi and welcome,
I don’t think so. First, officially Cubase sports Windows 10 only. I’m quite sure it uses some graphic technology, which is not fully supported even in Windows 7 (but it might work, if you are lucky), but it will most probably not work in Windows XP.
Second, Cubase 10.5 is 64-bit only. Most probably, your Windows XP is 32-bit.
In any case, you can always download Cubase 10.5 AI Trial and try it by yourself.
