I was also following the same problem when deploying my project backend. You can uninstall the bcrypt from your project but keep the "bcrypt": "^5.1.1" or whatever version you are using in your "dependencies": {}. Do the following steps:

1. Uninstall bcrypt
2. Add the following the line to your "dependencies": {"bcrypt": "^5.1.1"}
3. Now deploy your project on render.

Hopefully, this will solve the problem for you as well. If not, let me know here.
