Just posting a general link to the patch notes section:
Patch Notes - Crate Entertainment Forum
You’re probably thinking about 1.1.4.0, here…
…which featured this:
…and in which case means you would likely want to download 1.1.3.0, which released in July of 2019…

Unfortunately when downloading Steam stuff via the guide above there is nothing you can download that gives you specific PATCH VERSIONS - sadly, it doesn’t work that way - you need to find the necessary files via the date that they were released, which is why I mentioned the month and year that 1.1.3.0 dropped for you above.
Keep in mind that you would also need to find and download the correct files for everything: the base game, AoM, FG, Crucible if you have it etc… everything needs to be on the same page with each other and they all have separate downloads.
