Plugin conflict with subpages

I have a rather unusual issue. I’ve just created a website and uploaded the plugin. However, every time I activate the plugin, it prevents my subpages from loading and causes a “Page Not Found” error. If I deactivate it, the subpages work fine.

Unfortunately, my site is a podcasting site and this plugin is rather essential to the site’s operation. My WordPress version is 6.5.2 and I noticed the plugin hasn’t been tested for this version.

Any advise would be highly appreciated.
