Hi kalehacell, thank you for taking the time to report this bug!
Have you noted if this happens predominantly at or just after startup, or at any time?
Does it open a new tab with about:blank in the address bar, or an empty address bar?
If you know how to reproduce this issue, would you be able to share a screen recording of you reprodcuing this issue?
Thank you for your help in making Orion a better browser!
