Well, what it cannot find is a symbol file that isn't to be found within the game's folder:
~/Downloads/WalkingTankWarrior - Linux$ find . -iname \*.sym
This command finds no file either. So renaming the folder doesn't help any.

Ah dam sorry about that I have just disabled the download for it now!
A forum in google with the same error lists
"For those looking for an answer, try specify opengl version when running your game, my situation here is adding “-opengl4” and finally got it ticked." Maybe see if that works?
also saw using "-gpus all" can help with nvidia cards!
