Garrysmod keeps crashing frequenlty ( crash dump inside )

Hello

My garry’s mod has been frequenlty crashing on large maps after the garrysmod patch, so I have reinstalled whole gmod deleted everything and reinstalled didn’t solve it.

So now I turn to facepunch for help.

Crash dump: http://dumps.metastruct.uk.to/dumper.py?dump=hl2_160330_crash_2016_4_17T22_44_11C0.mdmp&key=PN-MNObLh6tGyHcwy0UcI7eU99S_MHiJcOtg0VpIwYC1KHx-4Z3FGvfh6ji0iUTUEnYNhgsTUjpfvoK3DXxBeSdzGMHpsEJA_zXELe86iaJ7i1JveVT9Mqezn3II9nS0wOqOpM0O92gjTofPj_DhJhqXTc4mBUIhVwtQB-laRcM=
