your robot supports processes built on net6.0-windows7.0, but your process Package Test 1.0.3 was built in net8.0-windows7.0 which is not compatible with your robot version.
Starting with 24.2, the Studio and Robot will move to .net8 as a runtime which will lead to the following situation: Micro-automations built/modified/published with Studio 24.2 won’t run with Robot 23.12 and earlier.
To solve your actual issue, you have two approaches:
Approach #1
Install a Studio version that is matching the robot version.
Open the existing project and debugged it. Make sure it is compiling fine.
Build the package, deploy it, and then install it on the robot VM.
Approach #2
Upgrade the robot to match the Studio version that build it. Should be something in 2024.2 or higher.
