This issue has been persisting for years, since about Linux Mint 17, or at least since 5 years ago. I've reported it back then, still nothing has been fixed. If you edit files via .gvfs in Linux Mint, and using Geany, keep the files open for a while, about 10 minutes, and Geany will freeze, not allow you to save the file, (even though frequently pressing CTRL+S is a reflex), and freezes all desktop. The only thing one can do in these cases is kill geany's process, but then, you start coding again what was lost since last save. While it's hung, you also cannot start a new geany instance. Current version of geany: 1.38 "Sulamar", (built on or after 2021-10-14), Using GTK+ v3.24.33 and GLib v2.72.4 runtime libraries, on Linux Mint 21.3 Vera (just updated about a day ago, issue is the same on all Mint versions since about 5 years ago !)
