Can I safely say that this is deprecated now then?

https://robertsspaceindustries.com/spectrum/community/SC/forum/51473/thread/launcher-error-6000

And is there any updated documentation on the specific error codes that are being thrown instead?

Hello @Karga11 !

Sadly it is not deprecated. The documentation is a very good list of workarounds that can help to solve these issues.

We will not see the Error code 6000 anymore, but we are just starting to list the Errors we get from the game.

So far the main codes are: 3221225477 / 3489660927 / 732819469 / 732823392 / 732823393 / 732823385 / 60097 / 60101 / 206 / 207 / 210 / 30 / 2147483651

We are going to investigate to fix these issues and create documentation to list workaround.
