IndexError while running build.py

[xSqne]

Hello, I tried to compile the source code by following all the steps mentioned (VS setup, 7-zip, python). However, I ran into an error while leaving the build process overnight. Here's the error:

`[30440/54785] ACTION //ui/webui/resources/cr_components/co...nge_listener:build_ts(//build/toolchain/win:win_clang_x64)
