What's Wrong?

when I start claude (I tried seceral directories) via plain "claude" command, claude launches for a aplit second, and then I get "trace trap claude" error and session abruptly ends.

i get different numbers bu always same message:

claude code version:
current: 2.1.12 · latest: 2.1.12

[1] 7442 trace trap claude
[1] 4451 trace trap claude
[1] 6442 trace trap claude

my machine:

Mac mini
chip: Apple M4
macOs: 15.5 (24F74)

What Should Happen?

claude code should launch and work normally - yesterday it worked just fine and I did not chaneg computer settings since then. I just went to sleep, woke up the next day and Claude Code from terminal stopped working.
