Error:Something went wrong with processing the default view and we have restored the filter to its original state

Go to database and Truncate ui_bookmark.

I think it will fix the filter problem and reset it but it's not a solution fot the problem itself, if you add a filter that returns too much results, like 999 elements to the grid it will happen again.
That happened to me before, I think is something like a timeout I could only fixing it by updating the magento version.

Hope it helps :D
