Hello,
Please try deactivating all third-party plugins and keep only the theme-required plugins active. After that, switch to the default theme and check if the issue still exists. This will help us confirm whether the problem is coming from the theme or from one of the plugins.
If the issue is solved with the default theme, then you can activate the plugins one by one to find the conflict. If it still persists, please keep the third-party plugins deactivated and let me know so I can investigate further.
Best Regards,
