Windows 10: Can't install Microsoft .NET Framework 3.5 0x800706be

I've been trying to install .NET Framework 3.5 when attempting to play older games such as Hotline Miami and Skyrim, if that's relevant, but before I can play it prompts me to install Framework 3.5. When I attempt this, it takes several minutes to say "Downloading required files", where its bar freezes for a much longer time. From here I either have to force close the window, or wait for it to finish with the message:

Windows couldn't complete the requested changes.

The remote procedure call failed.


Error code: 0x800706be.

I've also tried installing the Framework through Control Panel > Turn Windows Features On or Off, but it results in the exact same problem as above. Each attempt takes a long time to even try, and no forums I've found online have helped at all.

My specs are below:

OS: Windows 10 Home 64-bit

CPU: Intel Core i9-9900K

RAM: 32GB

Mobo: ROG MAXIMUM XI Hero Wi-Fi

GPU: NVIDIA GeForce RTX 3080

Windows Drive: 465GB Samsung SSD

System Version: 10.0.18362


Thank you.
