I faced this issue on 19c grid installation on linux 7. Our first steps is complete grid installation by using software only option.

That steps do not give any errors. But Grid background process such as ora.evmd,ora.cssd do not work.

Also srvctl command is not running.

So what we need? Here is the steps:

[root@standalone_server install]# ./roothas.sh
Using configuration parameter file: /u01/grid/crs/install/crsconfig_params
The log of current session can be found at:
/u01/app/grid/crsdata/standalone_server/crsconfig/roothas_2022-01-27_09-49-14PM.log

CRS-2793: Shutdown of Oracle High Availability Services-managed resources on ‘standalone_server’ has completed
CRS-4133: Oracle High Availability Services has been stopped.

Than you can run below command

standalone_server /u01/grid/dbs> crsctl stat res -t
