Safari Technology Preview 226 keeps crashing

[u/Muted-Reflection9536]

If I completely uninstall STP including all related files, I can use it temporarily, but when I try to start it after exiting it, it crashes and I can't start it at all after that.

There seems to be some problem with saving sessions or settings.

The regular Safari on my Tahoe DB7 had a bug where when switching tabs from the tab bar, the screen would go black for a while before redrawing, but this was fixed in STP, so I used it.

Are there any public archives of STP 225?

Just to be clear, I know it's a testing version and unstable, I just wanted to share that there is a crash bug.
