I know what you're thinking "This is just a repost", but just hear me out. I am sure I screwed up somewhere during the uninstall process. So what I did was :
Install "Vroid studio" using wine. Then I realised that steam's proton does a better job in running this app in linux. So I decided to delete the wine version of VRoid and install Proton's version of VRoid. I thought I deleted it, but it just stayed in the menu. Without deciding to look it up, I deleted all the files of VRoid from the install directory, then uninstalled again. No results.
Then, after searching for some answers here, I found that wine has an application called "uninstall wine software" in the menu. But I think I also screwed up somewhere during wine installation because I don't have it.
Then I also found out that you can run the app using terminal. I open it and when I press "modify/remove" I get an error message saying that the app has no files associated with it. It gave me an option to remove it from the entries. I did so. But surprise, It's still there. It's just like become permanent. Wine can't even remove it. I tried deleting via the menu entry, still no results.
I use a linux mint.
