A few hours ago I tried the latest version of iPlug2 master. There was a build error while compiling in Visual Studio 2019 version 16.0.0:  
Error LNK2001 unresolved external symbol ""public: static class std::locale::id `std::codecvt<char16_t,char,struct _Mbstatet>::id" (?id@?$codecvt@_SDU_Mbstatet@@@std@@2V0locale@2@A)"`

I tried to make corrections in the ITextEntryControl.cpp file:  
#ifdef \_MSC\_VER  
- #if (\_MSC\_VER \>= 1900 /\* VS 2015\*/) && (\_MSC\_VER \< 1920 /\* pre VS 2019 _/)  
+ #if (\_MSC\_VER \>= 1900 /_ VS 2015\*/) && (\_MSC\_VER \<= 1920 /\* VS 2019 \*/)  
std::locale::id std::codecvt\<char16\_t, char, \_Mbstatet\>::id;  
#endif  
#endif

At the same time, the assembly was successful, however, when the plug-in was started in debug mode, a run-time error unexpectedly occurred in a completely wrong place, where in principle there could be no error - at least I had never encountered errors when initializing structures - `const IBlend BLEND_75 = IBlend(EBlend::Default, 0.75f);` , where there are no actions in the constructors other than assigning values.

How to make the plugin work without errors, I can’t imagine it possible, maybe someone has already encountered a similar error?

Yes, I had this when experimenting with MSVC BuilTools. In the end, it was gone. I don’t remember exactly how I think I made additional #define \_MSC\_VER 1930 somewhere in my files…  
Удачи

Does this method get rid of a runtime error? Everything is OK with compilation.
