Hi,

A safe and effective way to isolate the issue is to comment out parts of your custom module's code, especially sections related to models, views, or JavaScript that may be causing the problem. This allows you to test the system incrementally without deleting the module entirely. To further assist debugging, set log_level = debug in your odoo.conf file to enable more detailed logs during startup and module loading. This can help surface hidden issues that aren’t shown with default logging settings.

Hope it helps.
