Laravel Project Troubleshooting

My Laravel project is currently experiencing issues. I can’t run `php artisan` commands without encountering errors. When I do manage to execute a command, it takes an excessive amount of time and I receive a memory_limit error, despite having increased my `php.ini` to 8g. My attempts to manually clear the cache have not been successful.

I have made modifications to existing features in the codebase recently, which may have contributed to these issues.

Ideal Skills:
- Laravel Development
- PHP Expertise
- Server Management
- Code Debugging
- Cache Management
- Memory Optimization

Please help me resolve these issues as soon as possible. Thank you!
