Please follow the recommendation by @Yochanan before doing anything further. 
As a new Manjaro user, this may require some research on your part.
Following the links is usually a good start, and then asking questions to clarify anything you might not understand. It’s a process; you ask questions; we ask questions; the answers lead to understanding. Ignoring something doesn’t help anyone. 
Following Transition to the new WoW64 wine and wine-staging leads to an Arch Linux page which reveals:
The takeaway would be that 32-bit wineprefixes need to be re-created - the application (or game) would then need to be installed again in the new wineprefix. This would apply whether using WINE directly, or Bottles, Proton or via any other abstraction.
This is a fundamental change to WINE that impacts many/most 32-bit Windows games – it is therefore suggested to re-create wineprefixes.
The default wineprefix for WINE (proper) for example is ~/.wine.
You could simply rename (preferred) or delete it, and then attempt to install a random Windows application, which would begin the process of re-creating the wineprefix.
What the process would be when using Bottles or Proton, I can’t say. This is where your own research efforts are required.
You could also create a new Support topic1 – something to the extent “How do I create a new wineprefix with Bottles or Proton?” – someone might be able to point you in the right direction.

Quick tip (General):
Simply reinstalling an application may not have the effect you had hoped for: unlike Windows, Linux applications often have dependencies which may be installed with the package itself.
In some cases, it might be better to uninstall an application and install it again, rather than reinstalling.
sudo pacman -Rns <package>removes a package and any packages it depends on that are not being used.sudo pacman -S <package>installs the package again.
That said, it’s rare that this will actually fix a problem in Linux.
Information:
The AUR is not officially supported by Manjaro (or Arch Linux). If software sourced via the AUR is used, it is generally recommended to switch to the Unstable branch.
