Subject: [PATCH] fix(User): add null and array checks before session data
 operations

Ensure that session data is only processed if it exists and is an array. This prevents potential errors when attempting to cache or remove user session data. Updated methods `cache_set_userdata` and `cache_rm_userdata` to include necessary checks.
