The mod Bob's Adjustable Inserters mod (1.1.5) caused a non-recoverable error.

Error while running event bobinserters::on_configuration_changed
Can't destroy root element
stack traceback:
[C]: in function 'destroy'
bobinserters/control.lua:1189: in function 'destroy_gui_button'
bobinserters/control.lua:1197: in function 'create_gui_button'
bobinserters/control.lua:617: in function <bobinserters/control.lua:612>

I THINK this one is already fixed in the WIP version.

Yup, it is.

Seeing the same issue, is there a workaround I can use until the fix is released?

Same. Originally had the issue on a Macbook laptop. Thought it was just for mac. After update it is now present on my Windows Desktop.

Older versions are available for manual download here on the mod portal. You can download and install an older version manually, just don't update it in the game.
