Thank you for your response.
I found out that a certain plugin is causing the issue. I am currently addressing it.
I will message you if there are any updates.
Thank you for your guidance, Tamrat A.
The theme is custom made and I have not made any changes that would affect it. I will try the method you suggested and check the other plugins.
I was not aware of the Health Check and Troubleshooting. I will install it. If I have any other issues, I will send a message.
