500 Internal Server Error when using WCFM and Translate Press

hello
I am using the storefront theme with elementor pro and WCFM (plus multivendor) with Translate Press, and a 500 Internal Server Error occurs after I switch to the second language and click on any of the translated pages or products every single time.

I increased the memory limit up to 1024, switched themes, and turned off all the plugins except for Woo, and WCFM, WCFM Multivendor, and Translate Press, and the issue still persists.

The pages only work whenever I update the permalinks page without changing any of the settings.

Also, it only works whenever I delete the cache manually (autoptimize plugin) every single time.

The page I need help with: [log in to see the link]
