Just posting here to add this is also happening to other people. Would be happy to help give log/crash report if needed (crash seems wrong since it is not actually crashing), if someone lets me know how to access a log for when this happens.
For me also:
- Version 0.99.137-beta (WebKit 623.1.8.0.0)
- macOS Tahoe 26.1 build 25B78
