System.Runtime version issue after installing Aspose cells cloud in

I am trying to convert excel to PDF using Aspose cells cloud SDK in my project. I am getting a version mismatch issue for System.Runtime dll and some other dll here. My dot net framework is 4.8 and the max version of System.Runtime is 4.3.1. But they expect the version, Currently I can’t upgrade my dot net verison. Is there any other possible ways I can achieve this?

Please keep me posted in case of any suggestions/solutions.

@Saniston ,
We suggest retrieving the original code, adjusting the TargetFrameworks to match your required framework versions, and then recompiling it.
