Last update = instant disappearing of my community

This is the error message I got from uploading the last version of fluent community. I lost access to Wordpress instantly after uploading.

I have contacted FC support that told me what to ask Hostinger support, which is a mere AI bot. I confirmed all the steps it offered to do (such as deactivating several plugins), to no avail. It’s a catastrophe. I don’t know what to do.

Does anyone know what may have happened?!
