ESP32 Compilation Error - partitions.csv?

[simon_c1433]

Hello all, I am having issues with compiling sketches in the Arduino IDE for the Elegoo ESP32 WROOM-32 board. I have installed the 'esp32' and 'esp_bluepad32' boards in the IDE and the Espressif drivers. I successfully compiled and uploaded the Bluepad32 'Controller' sketch but was unable to connect a bluetooth controller. I restarted my PC, but now I cannot compile any sketch for this board as I always receive the same error:

FQBN: esp32:esp32:esp32
Using board 'esp32' from platform in folder: C:\Users\xxxx\AppData\Local\Arduino15\packages\esp32\hardware\esp32\3.1.0
Using core 'esp32' from platform in folder: C:\Users\xxxx\AppData\Local\Arduino15\packages\esp32\hardware\esp32\3.1.0

cmd /c if exist "C:\\Users\\xxxx\\Desktop\\sketch_dec19a\\partitions.csv" COPY /y "C:\\Users\\xxxx\\Desktop\\sketch_dec19a\\partitions.csv" "C:\\Users\\xxxx\\AppData\\Local\\arduino\\sketches\\5215E0CD0EFE37AE427A75ED253DE93E\\partitions.csv"
exit status 1

Compilation error: exit status 1

I have 'ESP32 Dev Module' Selected as my board.

Things I have tried so far:

Removing and re-installing the board in the board manager
Clean install of Arduino IDE
Finding 'partitions.csv' in another folder and copying it to the folders given in the error message

Any assistance would be greatly appreciated.

Thank you

Have you checked to see if you are tripping on one of the breaking changes in Rel 3.x of boards? Have a look at THIS
if you see any of your libraries impacted, roll back to 2.0.17, see pic

Thank you for your suggestion. I switched to 2.0.17 but still get the same error message. I have verbose output selected in preferences for compile and upload but the error above is all I see. It is strange to me that it worked flawlessly the first time but now I can't even compile an empty sketch

The plot thickens.....
After reading this post I tried to open cmd in Windows to run the command listed in the error message and its not working. It seems Arduino IDE is trying to run the command via 'cmd' and cannot hence the error.
Running the command in Powershell and then deleting the Autorun key as per this post seems to have solved things and I can compile again
