Suspending a Windows 11 ARM VM in Fusion 13 is an iffy proposition because of the lack of VMware Tools to provide host/guest coordination and soft power operations. Perhaps this is why you lost the keyboard.
I’d recommend using the 2023 Tech Preview if you want to suspend the VM. It has Tools that do provide the soft power operations. An upcoming Fusion release later this year should contain these tools if you prefer to wait for a GA supported Fusion version.
