Hello,
could you please let us know what kind of project you have (which cameras / sensors and how many)?
Do you have this issue on the same project or on different projects?

As a workaround, you can use previous version of tracking.
Please go to 'Tracking' tab, open 'Advanced Tracking Settings' at the bottom, and check 'Use old tracking algorithm' checkbox.
This option is project-specific, so need to be set in all projects.
