Heroic Games Launcher released version 2.22.3 as a hotfix to address issues caused by the previous version, 2.22.2, which unintentionally created a "umu inside of umu" command that broke game launches for several Windows titles on Linux. The faulty routing of Windows games through the Unified launcher for Windows games on Linux (UMU) led to failures in games such as Lord of the Rings Online and Satisfactory, prompting users to disable UMU as a workaround. The 2.22.3 update rectifies this issue by adjusting the internal logic without altering existing store-manager functionality, allowing games to launch correctly again. The development team hinted that a major version is on the horizon, showcasing the interconnected nature of the Linux gaming stack and the rapid response of the open-source community to fix regressions

Heroic Games Launcher 2.22.3 Hotfix Repairs Broken Windows-on-Linux Game Launches

Heroic Games Launcher released 2.22.3 today, a hotfix that repairs a regression shipped earlier in v2.22.2. That earlier build rewired how the launcher routes Windows games through UMU, accidentally wrapping every game in the runtime and producing a broken "umu inside of umu" command that stopped launches cold. Players reported failures with titles like Lord of the Rings Online and Satisfactory, and the only workaround was disabling UMU in settings entirely. The fix stops the double-wrapping without disturbing existing store-manager logic, and the maintainer hints a major version is coming.
