Other Steps to Reproduce

I tried using the Dev URL as well as the stable URL. I also tried completing clearing out the staging folder for the Arduino IDE and re-installing the package. I also tried completely deleting the esp32 folder under the AppData folder but I still received that same error. None of these error occurred when installing v3.3.4 of the package.

I have checked existing issues, online documentation and the Troubleshooting Guide

@ryancasler - please try again. I has worked fine when I upgraded to 3.3.5 (IDE 2.3.7 Win11)

@ryancasler - In order to test it better, I have deleted cache files from

C:\Users\esp\AppData\Local\Arduino15\staging\packages

It installed 3.3.7 correctly again.
Try deleting all files in this folder and installing it again.

@SuGlider - same issue as @ryancasler , exactly the same debug message. Deleting the staging/packages folder does not help, same error again. Using Arduino IDE v2.3.7, Winsows 11.
