Done! Thanks

These look to be corrupted images which is caused by some type of hardware problem.

You see nothing like that in the actual RAW files on your computer?

What happens if you export to TIF format?

Also what camera are you using?

Take one or two of the RAW files and upload them to some place like DropBox and post a public link to them so they can be downloaded and checked on our computers.

This is the link with 2 sample: https://www.dropbox.com/sh/tzoqbwe1tt97ajg/AADrJraMmqQhQv7gmrxLjLYAa?dl=0

My problem is that the same picture can have a different output, if I retry export, but on my older PC I don't have this problem (with the same original file).

Also in TIFF export I've the same result.

My camera is a Canon EOS 7D.

Tested the files on my machine and they export without the colored blocks. I would guess that you are indeed dealing with a hardware issue on your machine. I would run diagnostics such as memtest and such.

Might be off on this.

In LrC bring up preferences, open the tab that has your Camera RAW CACHE setting in it, and purge the CACHE

Yes that would effect Develop module only, but...

Also, close LrC, delete the Library previews.

Restart LrC, retry.

I tried what was indicated, but I got the same result. On the Laptop I tried and exported everything without any problems.

[matteo_casoni]

I'll try to search a solution with Adobe Support. I've uninstalled and reinstall LrC but Nothing was changed. 

[Just Shoot Me]

I downloaded your files and then Exported them from LrC 9.4 as JPG images. Nothing wrong with them on my system.

You also say.

That would indicate a hardware problem on your other computer that is corrupting the images on Export and NOT a problem, bug or whatever you want to call it, in LrC.
