On desktop Word file is corrupted, but I can open it online or with Libre Office or WPS...

Describe the bug
Hello, I create generation of word file from dotx template. But in desktop Word Office app I can't open file, but with another ways, I can open (WPS, Libre Office, Google Docs, Online Office)
What the problem? Is this because I clone dotx file and generate docx?
