iMac Won't Boot After SMC Rest, Please Help

I reset SMC on my iMac and now it won't boot past the Apple logo. The loading bar can only fill about 3/4 of the way, and then it suddenly shuts down. I've tried booting my iMac into Safe Mode, but still have the same issue. Any idea?

The same issue happens in Safe Mode indicating that this problem is not caused by third-party issues and software conflicts.

Try a hard startup. That is to press the power button for 10 seconds to turn off your iMac first and then press the power button to try turning on your iMac.

Still no luck? Boot your iMac into iBoysoft Mac Recovery Mode to rescue files from your unbootable iMac first. Then, run Disk Utility First Aid in Recovery Mode to check your startup disk. First Aid will also repair the found tiny errors on the startup disk.

If First Aid fails to fix the startup disk errors and make your Mac turn on, go to reinstall macOS in Recovery Mode.

If, unfortunately, your iMac still can't boot past the Apple logo after trying the mentioned tricks, you need to contact Apple support to get some points.
