Alec (Dec 16 2025 at 20:30): Alec (Dec 16 2025 at 20:30):I'm trying to isolate this down to a MWE still but in the meantime through I would see if anyone is familiar with this issue. While printing a very large nested tuple with various data (dicts, custom types, arrays) in a REPL session on 1.12 on Windows 11, Julia crashes:
Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.

It didn't do this on 1.11 and it doesn't crash when running julia --project=@. -E '[command that returns tuple]'I removed OhMyREPL from my startup. Will post more information as I can diagnose it.

Alec (Dec 16 2025 at 20:55):I was able to replicate this with two different users, but a restart of Windows seems to resolve the issue. Windows hadn't been restarted since installing Julia.
