My 2016 IMac is stuck in a boot loop & Ive exhausted almost all of the recommended support solutions

So my iMac has been stuck in a boot loop for going on about a month and a half and I’ve been trying everything I can think of to get it restored to normal, but it seems like nothing is working at this point. Here’s a list of the recommended solutions. I’ve attempted so far with no success. - resetting smc - resetting nvram -unplugging all peripherals and booting -unplugging Ethernet and booting - using disk utility to run first aid on all of the drives - Restoring from Time Machine And just now I reinstalled the OS which after completing has gone into the loading screen where it now says less than a minute remaining. Since it’s been about 15 minutes, I’m beginning to fear the worst since it seems like it’s stuck in a boot loop again, which means i’m all out of potential solutions and starting to fear this might be a worse case scenario Can someone please tell me there’s still hope for my iMac and lmk if there are any other troubleshooting solutions available I should try
