I installed what you linked in a VM and it seems to be fine. I synced up using my code and it appears to be fine.

For my laptop I Uninstalled and Deleted “Brave-Browser” in AppData just to make sure all files were gone. I installed what you linked after I finished deleting and removing the files. I setup my Sync code and installed my extensions back.

Not sure if this will make a whole lot of sense but I will try.

I adjusted bookmarks in my VM. Which then it attempted to carry over to my laptop. Some bookmarks got missed so I imported my recently exported bookmarks via an HTML file and got everything where it was before. But I did end up crashing along the way.

Edit 1. Got another crash. Some of my folders for bookmarks got shuffled around and one disappeared. So I imported the most recent HTML backup of my bookmarks and re-organized them. Shortly after, maybe 1-2 min, I crashed.
