Apache does not start with undefined symbol: ap_ssl_var_lookup in multiple modules

[negrusti]

Perhaps after the upgrade to v96.0.11 on CENTOS 7.9 Apache does not start with errors in multiple modules:

Syntax error on line 2 of /etc/apache2/conf.modules.d/170_mod_deflate.conf: Cannot load modules/mod_deflate.so into server: /etc/apache2/modules/mod_deflate.so: undefined symbol: ap_ssl_var_lookup

Syntax error on line 2 of /etc/apache2/conf.modules.d/215_mod_headers.conf: Cannot load modules/mod_headers.so into server: /etc/apache2/modules/mod_headers.so: undefined symbol: ap_ssl_var_lookup

I guess that symbol is supposed to be defined in mod_ssl.so?
However,

strings /etc/apache2/modules/mod_ssl.so | grep lookup
gives me:
ap_lookup_provider
ap_hook_expr_lookup
ssl_var_lookup

Litespeed is working fine on the server, but I can't switch to Apache.
