Please re-run the installer. Looks like it was unable to download some files.

Deleted the rush folder and now i’m trying to select directory but after selecting dir
cmd closes
Please try running the installer from a terminal. You can do it by opening the terminal in the directory where you’ve downloaded the installer and running ./rush-init-win64.exe.

I am facing it now. I had built it previously and it worked twice for sure 
Before updating it, I had created a project “test”.
Updated rush successfully builds the project without any errors:
user@DESKTOP-BD6HS68 MINGW64 ~/Desktop/RushNew/test
$ echo ThisIsNewVersion
ThisIsNewVersion
user@DESKTOP-BD6HS68 MINGW64 ~/Desktop/RushNew/test

Which version of JDK do you have installed on your PC? It must be 8.
This is mine:

C:\Users\user>java -version
java version "1.8.0_281"

Java HotSpot(TM) 64-Bit Server VM (build 25.281-b09, mixed mode)
C:\Users\user>javac -version
javac 1.8.0_281
Please degrade it to Java 8

I checked javac
The Java compiler and the Java should have the same version to work maybe…?

javac is a part of JDK. You need to install JDK 8 for Rush to work.
Shreyash, in my case the both JavaC and the Java are same. But I do face a similar error to him?
Didn’t your issue got resolved? 
yes jdk 8 is installed.
btw after update i have only on file inside C:/Rush/rush
while there was many file before update
