I have received the mismatch message several times now. I tried twice to reinstall Monterey and the process ends after about 2/3 of progress with message that there was a problem. What now?

Just what errors are listed?
Make sure you backup your data. Yu may have to go to Recovery and the erase the disk and reinstall Monterey or what version is offered in Recovery.
Do you have a Fusion drive?
I'm having that same popup, followed this thread, and called AppleSupport. Got nowhere as she stated being it isn't popping up again, it seems fine. Went through all my speaker settings and gave up. I showed her this thread and she asked if I was experiencing any additional problems. I stated no but slhcrnp stated he/she was and I was concerned. Got nowhere, ended up hanging up.
first bad call with Apple..
First aid shows repeated errors
Thank you for your response. I still have AppleCare for this MAC so I will move to formal support now. More problems are emerging now and I need expert help.
Do you have an external drive you can install Monterey on?
If so I would try doing that and see if successful
Monterey won't reinstall after mismatch volume hash
