Hey i have a problem where after some time playing on a map i get missing textures on like half of the props even on these from gmod and half-life 2 with this mesage in console

About to crash! Failed to allocate optimal read buffer. Read from disk: 2796364 < buffer size: 2796364
Failed to allocate memory for texture read 'materials/viper/mw/weapons/357/weapon_vm_pi_cpapa_grip_stock_n.vtf'

or something like that
im also using MW base mods
and my gmod crashes really often
this only happens after the july 2025 upd
in launch options i have -heapsize 16777216 -dxlevel 90 -w 2560 -h 1440

Does anybody know how to fix it?
