Update: Any project I create that is big enough resolution for automatic titling, I get the same error message.

I cannot reproduce this with either the latest stable or current development versions of Blender:

Please try the latest daily build: https://builder.blender.org/download/

Go to File → Defaults → Load Factory Settings and then load your file to see if you still can reproduce this issue.

If the problem persists, please give us more clear instructions on how to reproduce it from scratch.

I downloaded the latest build and reset settings. When rendering any scene with [Performance -> Memory -> Use Tiling (enabled) ], the project renders, but when it is finished it produces the error message "error reading tiles from file." If 'Use Tiling' is not enabled or the resolution is not larger than the 'Tile Size', the error message is not produced.

I have tried adjusting other settings (Render Devices, Render settings, etc.) but none seem to affect the result. Eevee produces normal results as there is no tiling. I made no changes to Blender's settings, preferences, etc., this is with a fresh install of Blender on a new PC with fresh OS installation.

Edit: Sorry, wrote this before seeing the most recent comment.

For reference, this issue usually occurs if Cycles can't read the temporary file it saves during tiled render. This could happen for a few reasons:

The file can't be saved (E.G. The temporary directory it should be saved too doesn't exist, or requires admin privileges, or the drive it's saving too is full, etc)
The file get's deleted by some external program before Cycles can load it again.
The user changes the path Cycles is loading from after Cycles has configured a path to save too.

I'm with @mano-wii. I would try resetting factory defaults, saving the preferences, close and reopen Blender, then try rendering. This is likely to resolve this issue in most cases.
NOTE: PLEASE BACK UP YOUR PREFERENCES BEFORE DOING THIS.

Does this help?

Select from the top of Blender {nav Edit > Preferences}
In the preferences window, go to the {nav File Paths} tab.
You will see an option called {nav Temporary Files} and {nav Render Cache}. Change those to a location like a folder on your desktop.
Save your user preferences.
Close Blender.
Open Blender.
Render a scene with tiles. See if the issue appears.

I did as you said, changed the 'Temporary Files' path to a new folder on my desktop, saved my preferences, closed and reopened Blender. After rendering again, the issue persisted. This was with the default /tmp\ in the Output file path. It did still make temp. files in the new desktop folder, however the same error message was still displayed and there was no png render.

If I change the output file path to something else, though, then it works. That's fine I guess as I almost always change the file path to a folder associated with the project, but for whatever reason it always displays the same error if I leave the output file path as /tmp.

So I guess issue resolved..? I hope I was clear in my response here.

Just kidding, issue still persists. I created a new project, changed the Output location from "/tmp" to a desktop folder and the issue is back.

I'll look into the issue a bit myself and see if I can reproduce the issue and see if I could find any useful information.

I'm sorry, I tried reproducing the issue on my computer but was unable to do so. So it's hard for me to figure out what's going on.
I'm not really sure what's going on. All I know is that Cycles is encountering some kind of error either when writing the tiles (which results in issues while reading it) or reading a perfectly fine tiles.
Since I, and presumably many others, don't experience this issue, it suggests it might be some issue with your computer. Your storage device is too full? Or faulty? Or some folder/file permissions are wrong or something. Maybe there is a issue with Cycles? I don't know.

I'm sorry I can't be of much help.

Had the exact same problem today, and the issue was i had 0 free space on my drive where the temp file paths were. Since i mad more room it worked as before. Holpe it helps.
