Thank you very much for your interest and quick response. Could you share the contents of the vmx file in txt format for reference? Perhaps there are issues with some of our definitions.

You bet. Launch vs 1 hour.

Can you investigate your vmware-vmx process? Vmware Fusion process fine about RAM but vmware-vmx spending a lot of memory(exceed seperated memory)

1 Hour

Windows 11 Pro 25H2 26200.7462

VMWare Fusion Professional 25H2 (24995814)

Hi. Faced with same issue. Macbook Air M4, 24Gb, VMWare Fusion 25H2, Windows 11 25H2, after 1 hour.

Hello there, The VM that I had no issues with in version 13.xx is now being forced to shut down due to unusual RAM consumption during use. It shuts down directly on macOS with the usage shown in the relevant screenshot, without any errors on VMware. Could this be a memory leak? How can I determine this?
Device and environment information: 
 Macbook pro m3 max 48gb MacOS Version 15.7.3 (24G419)  Running Win11 ARM64 on VMware Professional 25H2 (24995814),  allocating 20GB of the 48GB RAM for the VM.
