NS sessions saved with python3.10 will not be opened with Exo-Striker on python3.11, and vice versa.

Apparently, nested sampler sessions saved with python3.10 will not be opened with Exo-Striker running on python3.11, and vice versa:

From python3.10 to python3.11 the error is:

<class 'TypeError'> can't multiply sequence by non-int of type 'Results' <traceback object at 0x7682c57777c0>

and from python3.11 to python3.10 the error is:

However, sessions saved in python3.10 and python3.11 will work fine if opened with the python3 version created.

This will likely not be fixed on my side since the ES will drift to python3.11 and python3.12. Nonetheless, fixes are welcome.
