I faced this issue, while trying to install the Unreal Engine on Ubuntu. The main culprit in the whole log was:

Unhandled Exception: SIGSEGV: invalid attempt to write memory at address 0x0000000000000003

This error line indicates that an unhandled exception has occurred, specifically a segmentation fault (SIGSEGV) caused by an invalid attempt to write to memory.

So, I resolved it by installing in a folder where I have all the permissions to read, write and Execute.

Because even if you try to give permissions and install in the current folder, you might face same issue while trying to build the project or deploy your game like here. So it is better to change the installation to a folder where you have all the necessary permissions.
