Issue persists for me after updating to Sequoia 15.4 Beta 2, Xcode 16.2. I tried deleting all simulators and this did not help.

Same issue for me since the latest updates to Sequoia 15.4 and 16.2. Whenever I attach to a Simulator and try to view any variable, the LLDB RPC server crashes immediately. FB16682372 Debugging physical devices still seems to work fine.
