That is unfortunate.
To solve your issue, I recommend seeking out other force power mods so that you have extra force powers to select to prevent being softlocked.
Here are a few suggestions:
https://deadlystream.com/files/file/1483-k1-force-enlightenment-power/ adds 1
https://www.gamefront.com/games/knights-of-the-old-republic/file/four-force-powers adds 4 but you can upgrade them, so it actually adds 12.
If these force mods are not to your liking, then until further notice, consider this mod incompatible with ShemL's Force Power Gain mod.
