Synchronet v3.21c for Win32 crashes upon startup with some version(s) of Microsoft C++ runtime

<DigitalMan> definitely looks like a crash
<DigitalMan> this is a fresh install or an upgrade?
<esc> This is an upgrade but I had the same behavior on a fresh install
<DigitalMan> weird that there's no log output
<esc> Reinstalled msvc++ 2015-2022 x86 and the crash is gone. Woot!

Apparently reinstalling or upgrading the Microsoft C++ runtime fixed the issue.
