Android version doesn't install on Pixel 7 Pro because its 32bit. Only takes 64bit :(
From what I read, apparently, it's possible to bypass the 64-bit limitation and install 32-bit programs in it.
Alternatively, you could try looking for some Android-on-Android emulators or virtual machines, so you can play an older version of Android without hunting down older hardware, without tempering with your phone's system, and without looking for bypass methods.
