Unsolved No non-QT project template in Qtcreator

[Eveho]

Hellow. I have a very strange issue. I need always to create c++ plain projects to solve problems, but there is no button "non-QT project" in project templates. Sometimes it appears, but next time fades out.

Button available https://imgur.com/3Aq8N44

What should I do to have this button permanently? Thank you.

Hi and welcome to devnet,

What version of Qt Creator are you using ?
On what distribution ?
How did you install it ?
