Is Forza Horizon 4 failing to launch?
After performing recent updates on my computer, I attempted to launch Forza Horizon 4 but it fails to open properly. It loads successfully, however, when I click “continue,” the game freezes at the current frame. My suspicion is that while simultaneously updating GeForce Experience and Fortnite, I received a notification regarding a potential graphics card failure – specifically an MSI GeForce GTX 1060 3GB ARMOR – and the Epic Games app crashed. The alert was titled "Graphics Card Error" in orange/yellow hues and stated “There appears to be an issue with your graphics card; please verify it meets the minimum system requirements and that you have the latest drivers installed.” This occurred during my GeForce Experience update. There was a single "OK" button on the notification, which I clicked to dismiss it. I ensured all applications were updated, closed background processes, and repeatedly tried launching the game, but the problem persists – an issue I hadn't experienced prior to today. – Nathan
Forza Horizon 4 consistently freezes during the “continue” process, locking up on a specific frame and eventually resulting in an "Unknown Error" message. This issue began after updating GeForce Experience and Fortnite simultaneously, leading to a reported graphics card error notification. Attempts to resolve it through driver updates, application restarts, and disabling optimization features have been unsuccessful. During the freezing period, ForzaHorizon4.exe is waiting on RuntimeBroker.exe, then switches to waiting on svchost.exe. The wait chain analysis reveals that ForzaHorizon4.exe relies heavily on RPC Endpoint Mapper (PID: 612) and RpcSs (PID: 612) processes running within svchost.exe. These RPCSS services are essential for remote procedure calls, but their prolonged activity during the freezing period precedes the game's crash. Task Manager details show these services as “Running,” and there’s no option to stop or restart them due to system permissions restrictions. The issue consistently manifests with PID 8100 for ForzaHorizon4.exe, while svchost.exe shows PID 612.
I recently experienced a problem with my computer after updating everything, specifically attempting to launch Forza Horizon 4. Upon launching the game, it loads normally but then freezes during the “continue” process, getting stuck on a particular frame. I suspect this began when I simultaneously updated GeForce Experience and Fortnite, triggering a notification about a graphics card error (an MSI GeForce GTX 1060 3GB ARMOR) accompanied by a crash of the Epic Games app displaying "Graphics Card Error" stating there was an issue with my card and advising me to ensure minimum system requirements were met and drivers were up-to-date. The notification simply had an “OK” button that I clicked, resolving the immediate alert. I’d already updated all applications and closed running processes before attempting to launch the game again without success.
Following this, I examined the task manager using the "Analyze Wait Chain" feature. I observed that ForzaHorizon4.exe was waiting on “RuntimeBroker.exe” initially, then shifted to waiting on “svchost.exe.” After approximately three minutes of freezing in this state, the wait chain indicated “ForzaHorizon4.exe is not responding,” at which point the game displayed an "Unknown Error try again later" message. I attempted disabling GeForce Experience optimization but it had no effect; I’m running Windows 10.
Further investigation revealed that after a virus scan found nothing, I revisited the wait chain analysis. It showed “ForzaHorizon4.exe” (PID: 23560) and “svchost.exe” (PID: 612). Examining svchost.exe revealed two related files: "RpcEptMapper" (PID: 612) and "RpcSs" (PID: 612), both running under the RPCSS group, which handle Remote Procedure Calls (RPC). These files persist in the wait chain for approximately 3-5 minutes before “ForzaHorizon4.exe is not responding” is displayed. I lack permission to stop or restart these essential files. Additionally, attempting to access the Event Viewer resulted in an error message stating "The service cannot accept control messages at this time," occurring while Google Chrome was open.
I’m seeking assistance as the issue persists despite my efforts. Note that thread 8100 is associated with ForzaHorizon4.exe within the FH4.exe file, but no corresponding thread exists for the svc.exe file.
