Brave sometimes forgets my pinned tabs after restarting

Hi, I have noticed that some of my pinned tabs occasionally disappear after I close Brave and open it again.

I have Brave set to continue where I left off. Most of my normal tabs return correctly, but sometimes one or more pinned tabs are missing.

I have already restarted Brave and checked the startup settings. I am using the regular stable version on Windows.

Is there another setting I should check, or could an extension interfere with restoring pinned tabs after a restart?
