Windows 10: .Net Framework Install corrupt and now fails

I opened an application that uses .Net Framework 3.5 on Windows 11. This prompted the install of the program, however the application used was already running and caused my PC to crash during the install of the windows framework. Upon rebooting Windows framework will not install and gives me an error now. Error code 0xca020007
