Ccache: error: execv of ... failed: Permission denied while compiling android kernel, how to fix?

Question

Android

I need to compile the Helios pro kernel from source.
I downloaded the necessary libraries, kernel sources and toolchain. I configured the kernel with make menuconfig. I write make modules_prepare, but here ccache gives an error: ccache: error: execv of home/maks/OTG/compx/aarch64-linux-gnu/bingcc failed: Permission denied
Tried chmod +x [compiler files]
PS - /home/maks/ OTG/compx/aarch64-linux-gnu/bingcc failed - the path to the toolchain.
Here is the full output of make:
