I tried, once again to update to the latest beta from 13 February. 5 crashes and hangs within 2 minutes. All crash logs sent to Apple for review, dont know if that helps anything. I am back to Version 0.99.122-beta (WebKit 615.1.11.7) restored from my Timemachine.
iMac (macOS Ventura 13.2.1 build 22D68), Intel 27".
I dunno whats wrong, at some point, I guess, a clean install would be an option, I just hate losing all my bookmarks, tabs and sessions that would need re-validation, e.g. onllne banking etc..
