No manual save means game breaking bug is game over

I've hit a bug in chapter 2 - find Voss' office. I've to open a hatch but it won't open. I've restarted the checkpoint but it jasnt fixed it.

Not having any manual saves to revert back to mean I am now stuck and cannot progress. My only option is to restart the game from the beginning and even then there is no guarantee this will resolve the bug.

I've been enjoying the game so much but now have no option but to abandon it and hope thst they come out with a fix.
