Ah, my apologies, I had high contrast mode set inside the vm to make it dark mode without activating windows license. I now see that's what was causing this issue inside the electron based Eve Launcher.

Ah my apologies, I had windows inside the VM set to high contrast mode since you can't activate dark mode without Windows key activation. Now that I turned it off it works fine.

After trying this for a couple of days, I would like to clarify for anyone: App Sandbox is 100% viable and capable of running bots in parallel, and is a very performant and robust platform to do it on. Across almost all sectors including ease of use/setting it up, as well as performance it's outdone VMWare. Perhaps in the future a guide could be added to the onboarding as a second option to VMWare, as the game's required resources to run keep going up and up over the years.
