Based on what you've described, the issue might be due to browser corruption or outdated package version. You can try

Reinstall Playwright and browser binaries:

playwright install

Update Playwright and Chromium:

pip install --upgrade playwright
playwright install

These steps can help resolve crashes or unexpected behavior by ensuring you have the latest, uncorrupted versions of Playwright and its associated browser binaries.

[Tata0703]

I didn't encounter SEGV_ACCERR issues, but I did some research and found that the signal SEGV_ACCERR is often linked to memory access violations. Make sure your system has sufficient memory and isn't experiencing issues like low disk space.

[Tata0703]

I added a script for testing installation: https://github.com/PathOnAI/LiteWebAgent/blob/main/test_installation.py

Please test playwright & chromium installation by running this script

python /Users/danqingzhang/Desktop/test_installation.py

Upgrading playwright and re-installing browsers worked for me. Thank you!
