My 'save as' window dialog box is not showing up

Hey folks, this morning for some reason my ‘save as’ dialogue box is not showing up (it was working fine until last night). I’ve reset back to default workspace but still nothing changed. I also tried going to preferences and checking ‘editors always on top’ like I saw suggested somewhere else but also to no avail. I’m in a setup with just 1 monitor

Does anyone have any clues? In Maya there’s some window preferences files that you can just delete and get all windows back to normal. Is it anything similar in Harmony?

edit: ‘file/open’ or ctrl+o doesn’t do any tricks either.
‘file/new’ works.

Thanks for any help and tips

Cheers
