Private Window closing the whole App

Description of the issue: When i open a private window and search something longer like ,steam community hub, it closes all the tabs and the app when i hit enter. Or if its just ,steam, it doesnt find the site and says it cant be reached. If you search ,steam.com, it finds it just fine.
Is it just that im dumb and thats how Brave private window works? Or is this an issue that needs a fix.
How can this issue be reproduced?

1.Have any normal tab opened.
2.Open a private window.
3.Search something up , not a site link specifically like ,steam.com, for example , just search up ,steam community hub,

Expected result:
Just like in normal window , i get results with different sites and links.
