Gnuplot kernel is stuck in 'busy' state

Gnuplot is installed, is in PATH and by itself works correctly. Notebook is also works fine with different kernels (python, lua, c++). The gnuplot kernel and the metakernel are installed with pip. I also added required by metakernel commands to ipython_config.py, which are being executed on start. The kernel itself can be started but when I try to run a cell the kernel creates a new gnuplot.exe process, then it becomes busy and stays busy until I manually shut it down. It also can be loaded with %load_ext function, but when I run %gnuplot ... I get the same result. I tried both ways of execution in both jupyter notebook and jupyter console. There are no error messages whatsoever, it just gets stuck.
