Shell state corruption after Ctrl+C interruption causes 'break' errors in subsequent commands

[lu0]

Describe the bug
After interrupting a command with Ctrl+C , subsequent bash alias commands sometimes output errors like bash: break: only meaningful in a for', while', or until' loop" and "bash: 2: unbound variable`. The error seems to be inconsistent as it sometimes disappears without clear cause

To Reproduce
Steps to reproduce the behavior:

• Let's assume I have pre-commit hooks set up in a git repository
• Then run git commit which triggers pre-commit hooks
• Interrupt the process with Ctrl+C during hook execution
• Run an aliased command (such as LL)
• Throws the error bash: break: only meaningful in a for', while', or until' loop`

Expected behavior
After interrupting a command with Ctrl+C, subsequent commands should run normally without any leftover error messages about break statements or unbound variables.

Screenshots
NA

Desktop (please complete the following information):

• OS: Ubuntu 20.04 LTS on Windows 10 x86_64
• Desktop environment: NA
• Shell: Bash 5.0.16
• Repository version: latest (tbd)

Additional context
Seems to be related to the state of the shell after interrupting commands. The error specifically mentions that break commands are being executed outside of loops, I think this suggests that an interrupted script might be leaving the shell in an inconsistent state. some environment variables or shell state isn't being properly cleaned up
