I removed my steam machine from the trusted devices so that I have to enter the steam guard code again.
Unfortunately I cannot enter the code as no input field is rendered in bpm.

Steps for reproducing this issue:

1. Remove steam machine from trusted devices
2. Next system start shows pop-up "you need to enter validation code" mail gets sent
3. After pressing "OK" there is nothing rendered no input field just blue background and select and done at the bottom
