Why won't my computer shutdown

Question

Hello guys I am a student programmer and a gamer on my PC. I have been going to shutdown my computer and I'd hit windows --> shutdown options --> shutdown and the run command shutdown /s /t 1. These shut down the OS but then reload windows afterwards. The only way to shut down my computer is force shutdown. I don't know why this is I have done a few things but they shouldn't affect anything:

• I downloaded some of Microsofts add-on executables to create sleep command and these aren't installed just downloaded.
• I have a lot of apps and I have run through malware checks and there aren't any outstanding issues, I only usually get flags when I develop executables it always flags it in defender.
• I manually checked through some folders and didn't find anything outstanding either.
• I don't have anything in BIOS to prevent shutdowns

Thanks,
Ixonblitz

1) Open administrative command prompt and type or copy and paste:

sfc /scannow
dism /online /cleanup-image /restorehealth
powercfg -h off

Post images or share links displaying the commands with results

2) Place the computer into clean boot:

3) Indicate whether turning off hibernation or using clean boot had any impact on the shutdown process

4) If there was no impact then run the V2 log collector:

Try run Windows Update and download and install all updates.
Try visit your device's manufacturer website and download and install latest driver (including firmware).
Try perform Clean Boot and if problem have been fixed, then enable each services and see which one causing this problem?
