solved by changing DocksLocked to false in global.ini

I had a similar problem and DocksLocked was already false. I "solved" it by renaming global.ini to something else.
Of course that meant reconfiguring everything.
In my case the device was not found. Like OP, i did nothing specific, i was recording as usual when OBS crashed. Then it would not start with the following error. All other programs work correctly:

...
error: alsa-input: Failed to open '': Device not found (translating from hungarian)

Using Linx Mint 19.2

I managed to solve this by changing the input in pavu. I switched my input, then tried starting OBS. if it doesn't work, change input and repeat. OBS finally opened with my webcam as an audio input. Then, make sure to remove the audio input from OBS.
