whenever i try to acess wiki, i get the following error

MediaWiki internal error.

Original exception: [RANDOM HEX NUMBER] 2023-12-21 12:30:42: Fatal exception of type "Wikimedia\Assert\ParameterAssertionException"

Exception caught inside exception handler.

Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.

for the random hex number, it changes whenever i reload or try another link

it also works sometimes, absolutely rarely, but sometimes it does
