Sorry to spoil the party, but this error on Win10 is way over-due, a simple search uncovers 1000's of URLs showing this, dating back to 2016 and earlier:
https://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install-winpc/microsoft-net-fra...
Will sparse everyone the details, as we've tried EVERYTHING under the sun, and there is NO WAY to bypass this error on several Win10 PCs we tried on.
SFC/scannow, dism, restore health, program files add/remove windows features, reboot after each try, clearly .NET 4.8 is PART of win10, builtin, this is the cli tool from github:
Currently installed "classic" .NET Versions in the system:
4.0.0.0
4.8.04084
yet, the silly Setup.exe keeps insisting that .NET 4.5.2 is missing somehow 🙂
All things are functioning, win update, win installer, no firewall, no anti-virus.... the TT log has this in it:

Pretty sure if right developer sees this, they can fix it. Please help pass this to the right developer, and fix this for good, why BLOCK users? give a warning and keep installing, at least until your code is fixed 🙂
