Ask your admin to whitelist virtualization software (such as VirtualBox) or use HyperV

Good you figured it out, i can imagine it's very confusing for people who only have Tor Browser & confused why the option only can be seen sometimes.
Yeah, i'd love to do that... But apparently there's a problem with virtualisation software on pc's that use bitlocker (at least that's what the team in charge of user's laptop's configuration has told me).
And since i manage the partitions on our power infrastructure, and i have full access to our vmware vsphere, I can make as many vm's as i want on both power and x86 professionally, so they don't want to bother investigating virtualisation sollutions for my personal use.
That being said, I find completely hiding options to be confusing for everybody... I mean, why would you completely hide options... That's just asking for discussion like this one. If an option is greyed out, everybody will immediately realise that the option exist, but for some reason it's not available to them.
Maybe i'll open an issue on github somewhere in the future... Maybe (if i find the time), i'll do a pull and see if i can fix it myself... However, this seems like a deliberate choice of (one off the) dev(s), so i doubt they would merge a "fix" anyways.
