Hi everyone,
Just wanted to give you a quick heads-up: DEVONthink 4.3.1 is currently hard-crashing on the new macOS 27 Developer Beta (Build 26A5353q).
It happens reliably as soon as I try to index a new folder, including one into a completely fresh one, or even move a file within the same database into a folder. The app instantly terminates with an EXC_BAD_ACCESS (KERN_PROTECTION_FAILURE) deep inside the Objective-C runtime when getAtomicStringNeuron is called.
Here is the relevant part of the stack trace:
Exception Type: EXC_BAD_ACCESS (SIGBUS)
Exception Subtype: KERN_PROTECTION_FAILURE at 0x0000006400610060
Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

3 DEVONkernel 0x103321eec getAtomicStringNeuron + 84
4 DEVONkernel 0x1032dd2d4 -[NeuralNet(Text) lookupString:] + 288
This is not urgent at all since this is only my test machine. Just wanted to let you know early so you can look into it. (Though I have to admit, out of 50 apps on my test machine, DEVONthink is the only one crashing completely so far… 
)
Best regards, Hartmut
