Upgrading to 0.93 frontend not loading correctly

So I just upgraded from something like version .67ish to the latest (0.93.1) and after upgrading (and updating all of my configuration to accommodate the changes) the frontend no longer loads fully. All I get is the blue bar and nothing else

When I downgrade to 0.92.0 everything works correctly, and I can see everything. I even went so far as to start with a blank config file, only containing the bare minimum to get home assistant up and running, but still nothing but that blue bar. I tried in multiple browsers, clearing cache, incognito mode, nothing changed. I read that there was a breaking change with the frontend component.

Convert frontend to do client-side modern JS detection (@balloob - #23618) (frontend docs) (breaking change)

However, no matter how I set the frontend: component, nothing works. I tried every combination of frontend outlined in the link above

frontend:
  javascript_version: auto\es5\latest (tried all 3)

and no change, still just the blue bar up on top. I’m probably missing something dumb, so if anyone has any ideas, I’m all ears.

Here is my bare bones configuration.yml that I tested, just to see if my full blown config file had issues

homeassistant:
  name: Home
  latitude: [redacted]
  longitude: [redacted]
  elevation: 376
  unit_system: imperial
  time_zone: [redacted]

http:
  api_password: !secret http_password
  base_url: [redacted]
  server_port: 443
  ssl_certificate: [redacted]
  ssl_key: [redacted]
  login_attempts_threshold: 5

frontend:
  javascript_version: auto

input_number:
  weekday_off_peak_number:
    name: Weekday Off Peak
    initial: 70
    min: 50
    max: 90
    step: 1
    mode: box

and here’s the log
