I am facing this same issue with my 2021 16 inch MacBook Pro with M1 Pro chip. Earlier when I bought this laptop it was working just fine with Monterey 12.0 but when I updated to Monterey 12.1 I started seeing this "Volume Hash Mismatch" notification. Also, all of my regular use applications like Docker, PyCharm, VSCode, Slack, Chrome & Python are now crashing every 10 mins. I contacted apple support & was told to reinstall the MacOs Monterey using bootable USB. I did that & it didn't work. Then I was told to reinstall MacOs via internet recovery mode. I did that too but it didn't solve the problem. I was also asked to upload the screenshots of issues so that it can be escalated to their engineering team. Never ever heard back from the engineering team. Then I was told to visit iVenus store(Apple authorised service provider) which is in Kothrud, Pune, Maharashtra, India. I submitted my laptop there and after a day I got it back with the freshly installed MacOS Monterey 12.1. The issue still persisted. I visited the iVenus store again the next day with those same issues. I was told to install application from App Store only as the third party application like Docker, Pycharm, Slack, Chrome, VSCode & Python are not yet supported by the Apple Silicon. I went to the website of these applications and pointed out the statement which says "Stable release for Apple Silicon". I was denied to provide any further services by the iVenus store as their support team concluded that it is a problem of the application and it has to do nothing with the machine. This morning I contacted Apple Support again and I was told to wait for another day so that they could escalate this issue to engineering team. I will be receiving the next call tomorrow at 11:30 in the morning. I pretty sure "incapable apple" wouldn't be able to solve my issues. I invested in a ****** product and yet the support team tends to congratulate me for using premium Apple product every time I got on a call with them. Here are some of the screenshot I took recently -

Incompetent & Incapable Apple here are few more screenshots - BTW Apple support has denied the repair, replacement or repair of my machine.

To the most asshole company of all time - Here is another issue while reinstalling the MacOS Monterey.

What a losers -
