Please note that you really should update all components of GVM (openvas, gvmd, gsa, gvm-libs), not only a single one. Especially as the components from different GVM major releases (e.g. GVM-10 and GVM-11) are not compatible to each other.
Most likely you had installed GVM from the raspbian repositories which can’t be mixed with source installations like this. You first need to uninstall the package manager based packages and install all GVM 11 (end-of-life, initial release 2019-10-14) - Greenbone Community Edition - Greenbone Community Forum from sources.
