Windows Explorer Constantly saying 'Working On It'

I ran into this issue last night and 24 hours later i'm at anyones mercy here.

I have four HDD's in my PC plus an SSD, everytime I open Windows Explorer/My PC in Windows 10, it just shows a green loading bar and never seems to stop. If I close the window and try to reopen Explorer I get the same issue but it says 'Working on it'.

I ran into this issue a few years ago and if memory serves me correct it was COM Surrogate causing the problem. I can't remember how I resolved it though.

I've done/checked the following:

• Checked my drives for errors. All 100% healthy, I have HD Sentinel installed too.
• Checked if there was any defragging going on, not that I could see.
• Ran the Windows Repair from Tweaking, didn't fix my problem
• Ran Avast and Malwarebytes to check for Malware/Viruses, nadda.
• Used CCleaner to clean the registry and remove thumbnail cache
• Updated Windows
• Rebuilt the index

On the last one for about 10 minutes it seemed to go back to normal, then back to showing the green bar.

If I stop COM Surrogate via Task Manager I can see my drives again, but as soon as I click on one I get the same issue, and it uses 10% of my CPU.

The only stable way for me to view my files is to turn off thumbnails in the Windows Explorer settings, which suggests something is very wrong with the way it's trying to generate thumbnails for images/videos/folders.

I don't know what to do next, any help or suggestions appreciated.

Did a clean boot, still no luck. I added all my drives to the indexing list so it's going to take a while to do that. Once finished i'll test to see if it;s stable or my last alternative is to do a clean install.

It's completely random. I was downloading images off my phone last night when i suddenly noticed some of the images weren't loading, since then it's been a pain.

Thanks guys, unfortunately none of the above worked.

Clean boot didn't fixed it, all my folders have the general template already, I don't appear to have the TDM or Intel Rapid Storage Technologies in my list of Services and i've also run a memory check to see if that's the issue. Nothing come back.

I've just installed Icaros and the issue has gone, though i'm far from convinced. Just a very strange situation. Will report back if it takes another turn for the worse.

Appreciate the assistance. :)

Not sure how to find out which one's causing the problem, clearly it's a video file as Icaros doesn't generate JPEG thumbs, though as far as I can see every video file is generating one perfectly fine now.

I can still see COM Surrogate running in the background but it's not crashing Explorer anymore thanks to Icaros.
