The Heroic Games Launcher has been released in version 2.22.3 - already the third hotfix in a row.

The launcher lets users manage and run games from the Epic Games Store and GOG on Linux. This hotfix fixes an issue introduced by the previous release that broke UMU for many users.

The last release broke UMU for a lot of people and this new Hotfix should fix it.

• Fixed an issue where UMU (Unified Module Utility) would be incorrectly nested when steamRuntime became enabled on non-native games (PR #5894, contributed by @CommandMC)

According to the maintainers, this is hopefully the last hotfix before the next major release.
