It sounds like you've been able to consistently land dev jobs, produce working software (it's not your responsibility to ensure the thing you've been asked to build is commercially viable), and build a good reputation (you mention good feedback and promotions), plus you've made a ton of money (most people make way less money than software engineers, and the average software engineer has not gotten a lucrative stock windfall). I think you've been very successful :)

> It's been a couple months and I have achieved nothing.

At my first software job it was said that a new hire typically wouldn't be a net positive for the team until they'd been there a year. You wouldn't necessarily have even been given a real task in the first two months, let alone gotten it shipped. Big companies have bureaucracy and gatekeeping (for good and bad reasons) and operate on timescales of months or years. By design, a new person can't unilaterally be productive. It's possible that investing the time to empower you to be productive just doesn't seem urgent to them right now - dealing with the fallout of a manager leaving may be much higher priority. You're on the payroll, they know you'll be around for them to utilize when they need you...

> If I can't work in the tech industry it would completely upend my entire life.

Based on what you've said, this fear sounds very unlikely to come about. Even if this company is dysfunctional and you need to move on, you have a history of being able to get tech jobs, and it sounds like you've made a positive impression on many coworkers in the past, so I imagine they'd vouch for you. And there's a ton of demand for developers right now, and a wide variety of companies to choose from!
