According to isaiah in his Stacks Discord channel, he has spent several evenings reviewing the crash reports that Dan sent him and was able to identify some of the causes of the crashes.
He is now close to releasing a BETA version to address the Tahoe-OS crash. For this, he is still looking for beta testers. So if you are seriously interested, you should reach out to isaiah. Since isaiah is most active in the Stacks Discord channel, that’s the best place to get in touch with him.
