Have not yet tested downgrading to v4.72, but have the same problem with v4.73.
If I try so tart Docker Desktop from the cli I see the following messages
[BUGSNAG] Loaded! In main process.
Electron binary was executed directly, will delegate to Docker Desktop backends
open Windows binary C:\Program Files\Docker\Docker\Docker Desktop.exe
[7488:0511/205557.343:ERROR:content\browser\network_service_instance_impl.cc:610] Network service crashed or was terminated, restarting service.
[7488:0511/205557.449:ERROR:content\browser\gpu\gpu_process_host.cc:1004] GPU process exited unexpectedly: exit_code=1
What information might be interesting for further investigation?
