Thumbnailer allows me to see a picture of my Embrilliance files, in my case PES format and it doesn't work.

Thumbnailer is made by Embrilliance and they said it is an Apple problem as some users do not have a problem. I have done everything Embrilliance said to do and no luck.

Thumbnailer is what the name implies, it shows a Thumbnail of my PES file, or it did before updating to Catalina. It does show a thumbnail of my PDF files. Without it working, it is like looking blindly at the file with no clue as to what it looks like.

This is a fellow user supported community, and Apple product teams do not participate here. They also do not fix third-party vendor software issues, as those remain the responsibility of that vendor.

On the Embrilliance Thumbnailer downloads page, they actually have a version 2.98 pkg (Thumbnailer298CatalinaSetup.pkg) that they claim was built on Catalina. But you need to grant the application full disk access in System Preferences : Security & Privacy : Privacy tab : Full Disk Access where you would click the + symbol and navigate to the Thumbnailer application and grant it full disk access:

As it is installed from without of the Mac App Store, you may also need to follow the Apple article, Safely open apps on your Mac, to pass the Catalina security validation.
