App doesn't launch in VM

[nburkitt]

Ubuntu 22.04 on VM running under Hyper-V. Manually installed Firefox (since default Firefox doesn't like VMs). Installation is successful, icon appears in "Show Applications." Attaches to Favorites bar. This app seems to have the same opinion of VMs as snap-installed Firefox. Here's syslog when attempting to launch:
