Cant install python 3.9.5 on newer windows images

Feedback & Bug Reports
1

Since the beginning of February, we are not able to install python 3.9.5 (using choco install python --version=3.9.5) on Windows executors. We haven’t changed anything in the problematic flow, so i dont believe the issue is on our end. We are not seeing this problem for python 3.7.5 nor 3.8.5.

Seems that the build-agent version has changed between working and failing builds.
WORKING AGENTS:

Build-agent version 1.0.105680-924e1373 (2022-01-31T21:01:13+0000)

Hi @Nave ,
Python version 3.9.7 is installed in the image already, so chocolatey is complaining that you are trying to install an older version on top of it. To use 3.9.7 just run:

py -3.9

Here is a screen shot of the error and how to use the existing version of python 3.9 that is in the image:
