Hi, Guys:
Today I tried to install win10 in my 2019 imac (27), it failed and re-start, and cant log in macOS system either. I tried to re-install MacOS, didnt work, error code is 69716. I checked its hard disk, seems the space assigned to win10 cant be formnow. How to install Mac OS now? Thx a lot!

yes, I did erase Macintosh HD, but still can’t do partition, error code is same: 69716. Don’t know how to fix it and re install MacOS.
Try repairing the disk with the 'First Aid' button circled below-
You can't make a partition- you'll just have to reformat the entire disk. Click 'Erase' in recoveryOS's Disk Utility, then reformat it as APFS, GUID Partition Map (if prompted).
cant re-install macOS after fail to install win10, error code:69716
