I cannot reproducue your problem even with chcp.com 65001 and
start "" cmd.exe ...

By the way, using tee for logging the output is not good
idea because stdout is not a tty. Due to this, less command
does not work properly.

Instead, I recommend:

@echo off
set CYGWIN_ROOT=...
set PROJECT_LOG_FILE=...

"%CYGWIN_ROOT%\bin\script" -q -a "%PROJECT_LOG_FILE%" -c "chcp.com 65001 > /dev/null 2>&1; /bin/bash --login"
