ofluffydev [1] filed an orphan request for lmstudio-beta [2]: Can't find any method of contacting the maintainers, the package is currently far out of date and needs more maintaining as it is a newer project, and has constant updates. Also, I would suggest create a wrapper instead of direct install since the app has auto updates. I can take over for this package if possible.
