Never seen that, looks like you running site on misconfigured localhost.
Check your memiry limit php settings.

My website is online not localhost... https://www.jordanindex.net
I am using php8 and memory_limit 768M  the host default value.

That error come from external library, not from Osclass. Try to use different PHP version.
