Crash when changing values in custom ai

[mammalian-hominid]

When in the custom ai change value screen, attempting to change the option highlighted results in a crash

Crash log gives the following info:

Error

HspError 31 WinError 0 Line -1 Ver 6120 Mode 0

3 .turn_end:pc ct:0
2 .main_init:Begin ct:245
1 .main_init:End ct:0
0 .pc_turn_init ct:0

I've tried changing the value after setting the other parameters as well as only changing the value parameter. Results in the same behavior regardless.

Currently running the game on Windows 10, version 21H1

Help would be appreciated : )
