Hi @olgalukashovasanz and thanks for your query. As you are using the Tobii Pro SDK then I would kindly redirect you to the Tobii Pro Support department directly who may be more acquainted with this issue.
This forum is principally intended for support with the Tobii Tech Consumer level eye trackers (4C, Eyex, etc) and their associated SDK’s.
Please get in touch with Tobii Pro Support team directly @ http://www.tobiipro.com/contact/contact-support/ for an answer to your query.
That being said, I noticed you already found the similar thread here related to “failed to start calibration thread”.. did you already try reinstalling the HTV Vive Drivers?
