Python quit unexpectedly

[gottk]

I am experiencing frequent crashes when using trezor-agent to sign my key for SSH connections to servers or when used in combination with Git. The issue appears to be increasing in frequency.

Upon crash, Python generates an error report indicating an unexpected termination.
The following stack trace is provided:

Steps to reproduce:

Use trezor-agent to sign a key for SSH connection or Git operation
Attempt to connect to a server via SSH or perform a Git operation (randomly crashes on git pull / git fetch or git push)
Observe unexpected crash and Python error report, it closes my terminal as a side-effect too, which is not great while being in the middle of a deployment.

Additional information:

Frequency: Increasing over time
Trezor-agent version: trezor-agent=0.12.0 libagent=0.14.7
Python version: 3.12.4
Operating System: Apple M1 Pro / MacOS Sonoma 14.5

Please help.

It seems like an issue with hid Python module:

Do regular trezorctl commands work on your machine?
