I was having the same problem the last few days, it worked yesterday after I redid it with the new unsigned apk, but it isn't working again today, might need another fix.
Also, curious, what's the difference with the bypass apk?
I was thinking the same thing, had the same problem on NOX Player, both on a 32bit 7 client and a 64bit 9 client, but switched to LDPlayer, went and rooted it and did everything again on that one, and it worked fine
