Rolling back the update is the most effective initial step to resolve issues that started occurring after an application was updated. This suggests the update may not be compatible with the user's system or contains bugs. Rolling back to a previous, stable version can restore functionality until the issues with the latest update are resolved. Reinstalling the same updated version of the software could re-introduce the same problem, while performing a system restore may be too invasive for a problem isolated to a single application. Installing more RAM would not directly address software crashes caused specifically by a recent update and may not be related to the system's hardware capabilities.
