Do you render with GPU or CPU?
Does blender crash when you set CPU for render?

It seems like you're "out of memory" on GPU and/or System (PC or Notebook)

try running blender with --debug-gpu-force-workarounds => and start Blender again.

which linux, on mesa or proprietary drivers?

edit the bug report with:

open blender-> menu -> help -> report a bug

blender will tell you about which machine you are and what drivers you use.

When I was playing with manual retopology and tried to add material to the wrapping object it crashed again with the following log:

Trying recommended Nvidia driver for Ubuntu does n't seem to have the problem,

Blender quit

Changed status from 'Open' to: 'Resolved'

I guess this can be closed then? [since we have a working driver?]

(feel free to comment again though if issues arise again...)

HI,
I ve got the same config (ubuntu NV 730GT ...) , and passed from 340.107 that crached blender -> to nvidia 390 ... driver and worked fine on every 2.80 2.81 and 2.82 , (in the additional drivers ubuntu directly in software and updates == easiest way to install the nvidia drivers)
used this one because the last driver 435 from nvidia website don't work correctly on my old config (wrong resolution, don't detect my vga screen any more)
if other drivers don't work u can also set rendering to CPU & "supported" features ... and works fine (but without CPU+GPU performance)

the error logfile was looking some thing like segmentation fault... before stoping app and was happening at any time while using blender 3d...

thanks for this topic that helped me to solve my problem.
Bye
