Paint.net not letting me use copy and paste

[MicrowaveHacker]

When I use copy and paste it crashes

the crash log says:

You need to reinstall the .NET Framework:

[MicrowaveHacker]

How do i uninstall the .net framework in the first place?

[Ego Eram Reputo]

Reinstall it without removing the existing installation.

[MicrowaveHacker]

I tried to do this but it just says .NET Framework 4.8 or a later update is already installed on this computer.

You must have Win 10 v1903. In this case, you'll need to run the System File Checker:
