Did I destroy my Mac HD?

After a couple attempts to re-install Big Sur, I started getting duplicate volumes of Mac HD. I'n my attempt to remove them I accidentally deleted all the Mac HD's on my disk utility, and then restarted the computer like and idiot.

It went into recovery mode, and then I had an issue trying to install big Sur because it was saying there was no longer a HD to install it on, so then with little research I read that I should then erased, renamed, and then reformatted one of the volumes that was there, and then called it Mac HD. I have no idea if this is correct, but it worked and I was able to install Big Sur.

Ever since the install, everything seemed to be working fine, until I started fcpx and it just kept freezing up, then I got a message saying I used up all my memory and I should close a program.

I have a 2018 6 core Mac book Pro i9 processor, with 1TB ssd, and 32 gb of ram, and I never had this issue before. Another strange thing is that I ran the Cleanmymac app, and it could not delete my junk files saying I don't have permission, and in disk utility my Mac HD keeps unmounted itself every time I restart, and I see another strange volume I don't recognize.

Did I totally destroy my HD?

Starting with Catalina, you have two volumes - one is Mac HD which is now read only and contains the OS and system files - it is sequestered in its own volume and neither you nor anyone or anything else can access it. The second volume is Mac HD - Data which contains everything else and has read/write capabilities - and it does not show up on your desktop (because the volume is part of the HD container).

So, your screenshot looks fine for Big Sur. If you reinstall without erasing, you will always get another Mac HD - Data folder. You can erase that as long as it is empty.

And, most importantly, get rid of that junk you have installed. It does absolutely nothing - if there is no access to your system, how could it? It will run in the background using your resources and messing with your drive.
