Polylang 2.9.1 annihilating site speed

I saw an update for Polylang and immediately updated.

After updating, the back-end worked as expected, but the front-end took 30-60 seconds to load.

I saw that there was a “Caching” fix. I’m running on LiteSpeed enterprise server.

I installed the rollback plugin and went back to 2.9 and everything works flawlessly.

Any idea on what would be the problem?

P.S. I’m also running Polylang for WooCommerce on the site.
