The overshoot hasn't caused failure due to functional limits, yet.
Water will fail first, it already is. Read up on aquafiers, at least snowfall can replenish annually (if it falls in the right places).

Aqufiers will fail. Subsidence is when the land sinks from water (or oil) extracted from aqufiers. The California's Central Valley has sunk about 28 feet since the 1920s. I'm sure that's sustainable...

In other news, 2-3 billion people experience water shortages:

(this is the current minimum overshoot in my opinion)
Food:
Worst food crisis since 2007, about 200 million face food ermegency or famine globally.

Political Problems: I won't even get into that.
What's the result of this? Migration.
There will be a lot of untracked migration and a ton of migrant deaths. Locals will resort to violence.
The bloody edge of all of this will be far away from the "first world" countries, where our politians are forced to promote endless growth because the other person will.
That bloody edge is called "global population control". We keep that out of sight, and wind turbines, I don't want to see that either!...
