Found the solution after so long. I needed the following function call

plugin_module_make_resident

in my module load function:

G_MODULE_EXPORT void geany_load_module(GeanyPlugin* plugin) {
    // Step 1: set meta-data
    // <snip>

    // Step 2: set functions
    plugin->funcs->init = projectview_v2_init;
    plugin->funcs->cleanup = projectview_v2_cleanup;
    plugin->funcs->configure = NULL;
    plugin->funcs->help = NULL;
    
    // Prevent segfault in plugin when it registers GTypes and gets unloaded
    // and when reloaded tries to re-register the GTypes.
    plugin_module_make_resident(plugin); // <-- needed this call

    // Step 3: register
    GEANY_PLUGIN_REGISTER(plugin, 248);
}
