This is an interesting thread !
I've tried to add what that guy did : adding a desassert of CS just after the CMD55, then sending CMD41 as well as doing spiRec() until it succeed or timeout (instead of re-sending the whole CMD55/CMD41 like the current library is doing).
Unfortunately, it still hangs on the same way as before.

Thanks ! it is appreciated. I'm using pin 16.
Indeed, very strange.
I've check PSU, I've 3.28V after the AMS1117, and just in case I've added a 100uF on 5V side, but it didn't help.
Also, it doesn't explain that it is working with the MapleMini and not the ESP, it is the same PSU.
Adding to my nightmare, I've tried to use other SDCards, formatted in FAT32, it is failing the same way, and worst, my MapleMini don't like them during volume.init().

Maybe there is something with your power supply.
Very strange......
