As the GitHub issue states, Joplin has been broken on Windows 32-bit for a very long time. Until recently, you were still able to make it run by doing some hackery (as described in detail in the issue), however as of today, it doesn't seem possible to make Joplin v2.13 and newer work, at least not by user-side hacks.
I suppose the 32-bit compatibility is still desired, thus the GitHub issue is also still open. I've got one 32-bit system myself where I'd like to keep the newest version of Joplin running, so I may try to look into the code myself (although with rather basic skills), however I can't say when this will happen due to major time constraints right now .
