Rewrite rules issues with latest Polylang version

Hello there ??

First of all, thank you for your great plugin ??

I have a weird issue with Polylang on one of my website. It’s a multisite website, that has been created years ago and have been updated (both WP and Polylang) every time it needs to be.

With WordPress 6.4.1 and Polylang 3.5.2, when I go on the Polylang settings page and save the settings (even if nothing changes), the single post page (and single CPT) are redirecting to the homepage. I have installed the “rewrite rules inspector” and I have this: https://snipboard.io/zGuW3U.jpg

If I go to the Permalinks WP page and save the permalinks, my pages are working well again. Here is the rewrite rules inspector screen: https://snipboard.io/yDxpq0.jpg

But if I go back to the Polylang settings page and save, the issue came back… If I downgrade to Polylang 2.9.2, the issue is also gone.

It seems quite similar to this issue, but I don’t use the PWA plugin… https://www.ads-software.com/support/topic/conflicting-rewrite-rules-breaking-single-posts/#post-17232417

Could you please help me?

Thank you,
