MacTeX Installation fails on M1 Mac

What you have is a singularly unhelpful error message. Basically, “something went wrong”.

You might try searching the file /var/log/install.log for clues. The file is long, but if you haven't installed anything else recently, the mactex installation log entries should be near the end.

Perhaps you have a full disk? Worth looking into.

Also, the mactex support list will be much more likely to help than texhax:
