Hi Nafiz,
Thank you for looking into my issue.
I followed all the steps you provided, including switching to the default theme and deactivating all plugins. However, the issue persists, and I’m still encountering the same error as I mentioned earlier.
Additionally, I realized I didn’t mention before that this problem only occurs with user roles such as Editor, Author, or any role other than Administrator. When logged in as an Administrator, I don’t face this issue. I also want to point out that before the 3.0.0 release, I was able to create courses without any issues when using the Author role.
