Has anyone had an issue with their IMAC freezing while loading Monterey?

I cannot thank you enough for your knowledge and time. I followed the link you provided and went to the section where it discusses the computer stalls while opening showing the Apple Logo and the Progress bar. I followed the instruction and had to unplug all accessories before it would finally finish the start up. It finally worked and I am typing this from the desktop.

Again, I am most grateful for your patience and persistence in working with me to resolve the problem.

When I tried to download Monterey the downloaded completed to about 60- 70% and then just froze. I restarted several times and it did the same thing. I then tried Recovery restart and it basically did the same thing.

How can I download Etrecheck when my computer won't open? I am writing this on my laptop. I believe my desktop and my laptop are synced through the Cloud. I sincerely appreciate your help and hope you understand that I am not very savvy with technology. Thank you.

I have even tried unplugging the computer and waiting several minutes before plugging back in and when I do so it immediately tries to restart but then freezes. This morning I tried to Safe restart-same result and Recovery restart-same result. Thank you again.

I am not very tech savvy but I do not believe I do

The freeze happened when I was downloading Monterey but I, quite frankly, don't know if the problem is Monterey or the computer. Thank you.

It actually starts and tries to open but then the white bar below the Apple moves until it gets to about 70% and then just stalls. It powers up but just won't open completely. Thank you.
