After installing the SharePoint 2019 KB5001945 Security Update, today all document libraries and lists show nothing but a blank page. This occurs even on the Central Admin site. Does anyone know the best way to fix it? Should we roll-back the CU? Anyone is facing the same issue?

Did you also install KB5001944?– user6024Jul 21, 2021 at 5:22

No, it wasn't installed. It looks like a language pack was installed without any other updates. It wasn't me, but I am trying to help someone with this issue.– Denis MolodtsovJul 21, 2021 at 13:13

1You must install both updates from each month, even if you are only using the en-us version of SharePoint Server. If a locale-specific update isn't available for that particular month, you must have the most recent loacale-specific update installed. Install that KB and re-run the Config WIzard.– user6024Jul 21, 2021 at 13:28

According to this article,
It is required to install both fixes (language dependent and independent) to fully patch a SharePoint server.
Have you installed both two fixes? Please install both fixes.

It is always recommended install both Language dependent and independent update ad then run psconfig wizard. Not sure if you can roll back SharePoint update unless you have taken Image level backup of SharePoint Servers and SQL servers
