Comment 11 for bug 1715339

It's likely your issue will be fixed by an updated version of Aspell (see bug #1714278 for details).

If you want to test the patched build it should be sufficient to replace "libaspell-15.dll" in your Inkscape installation directory with the one found in the /bin folder of [1] or [2] (for 32-bit or 64-bit respectively).

P.S. The issue was present in 64-bit builds of Inkscape for quite some time now. Maybe you were using 32-bit builds before?
