c harIDToTypeID "is not a function"

Since the latest update, previously working code containing the application Method 'charIDToTypeID' fails "charIDToTypeID is not a function".

Any ideas why and how to fix it?  I have a LOT of functions that use it.

Also the error "ActionDescriptor does not have a constructor" is occurring in code that previously worked OK.  Hopefully I can address that using Script Listener, but I do notice that it is showing changes (expansions) to the code from previous versions of PS.

FWIW, 'stringIDToTypeID' works OK.

PS 23.1.0

Win10

e.g.: var idslct = charIDToTypeID ( "slct" );
