I also have the same issue and i’m also on GoDaddy (managed wordpress).
Latest WP, latest polylang and, I assume, not an old version of PHP.
Here’s the content of _transient_pll_languages_list
a:2:{i:0;O:12:"PLL_Language":17:{s:7:"term_id";i:2;s:4:"name";s:7:"English";s:4:"slug";s:2:"en";s:10:"term_group";s:1:"1";s:16:"term_taxonomy_id";i:2;s:8:"taxonomy";s:8:"language";s:11:"description";s:5:"en_US";s:6:"parent";s:1:"0";s:5:"count";i:5;s:10:"tl_term_id";i:3;s:19:"tl_term_taxonomy_id";i:3;s:8:"tl_count";i:1;s:6:"locale";R:9;s:6:"is_rtl";s:1:"0";s:5:"mo_id";N;s:10:"search_url";s:31:"https://hmroads.com/language/en/";s:8:"home_url";s:31:"https://hmroads.com/language/en/";}i:1;O:12:"PLL_Language":17:{s:7:"term_id";i:4;s:4:"name";s:16:"Latvie?u valoda";s:4:"slug";s:2:"lv";s:10:"term_group";s:1:"2";s:16:"term_taxonomy_id";i:4;s:8:"taxonomy";s:8:"language";s:11:"description";s:2:"lv";s:6:"parent";s:1:"0";s:5:"count";i:4;s:10:"tl_term_id";i:5;s:19:"tl_term_taxonomy_id";i:5;s:8:"tl_count";i:1;s:6:"locale";R:26;s:6:"is_rtl";s:1:"0";s:5:"mo_id";N;s:10:"search_url";s:31:"https://hmroads.com/language/lv/";s:8:"home_url";s:31:"https://hmroads.com/language/lv/";}}
