Kahl's Jetpack no vertical lift bug (Game breaking)

[Paroxysm]

I have restarted the mission thrice now, every time upon restarting I switched Warframes (Mesa Prime, Volt Prime, Wisp), and switched from the drifter to the operator to test if that's had an effect.

Each and every time the result is the same, at the "Get to the dropship" section of Karl's questline (Veilbreaker), I am unable to generate any vertical lift from the jetpack itself, all of the momentum itself being thrusted forwards, with no more vertical momentum than the jetpack's activation vertical axis.

Which consequently makes it impossible for me to complete the Veilbreaker quest.

To clarify: I have not rebound my spacebar.

• How can this bug be reproduced?
• Merely enter the Veilbreaker quest, and progress through Karl's story progression, 100% of the time this has happened to me in my 3 attempts.
• What was happening before the issue started?
• Nothing of interest, game and quest worked as expected.
• Can you provide your build and game settings?
• Custom, (Borderless, vertical flip experimental setting enabled), DX11, classic graphics, unlocked fps, all low except: video memory, texture quality, enhanced shadows, all lighting effects (no bloom, depth of field, distortion).  
• RTX 2060, i7 10750h, 16GB RAM 3000mhz (dual channel), Windows 10. 
• What kind of squad were you in? Solo, host, client?
• Solo.
• Can you share any images or a video of the bug?

I have the exact same problem.

For anyone that has this issue, try to reset your keybinds to default, this is what fixed it for me, despite never rebinding my spacebar.
