I notice the following error on MacOS logs (Console.app) while Cool-Retro-Term beta shell being displayed:
kernel SID: 0x0 task: <decode: mismatch for [%p] got [SCALAR private sz:0]> buffer: 0x0 buffer->fClientTask = 0x0 not found

Mac Mini M4 here with MacOS 26.3 release candidate. I have developer tools and some experience, I build some snapshots.
