I suggest you check it better. I found a bug on my site after updating your plugin. I then tested your plugin on a new wordpress site with only your plugin installed. Therefore, the problem is in your plugin, because no other plugin was installed on the site, and no changes were made in the wordpress settings.
I recommend you check the plugin again. You can detect the error easily. Watch this video: https://youtu.be/TdZgyg7U7to
