[Resolved] Issues with ‘Site Library’ Install with PHP 8.0.6 and 8.1

Hello,

I recently tried to install GeneratePress on a server running PHP 8.1 and 8.0.6, which worked fine. However, after installing a site from the library, I received a critical error, as seen below. Once we changed the PHP version to 7.4, the error remained as a warning but allowed the site to function. I would ideally like to use 8.0 or 8.1. It seems to be related to the GenerateBlocks plugin, upon deactivating that plugin, the site, while looking rather strange, functioned.

I would appreciate any help that could be given, thank you very much!
