Community Manager@texasdfwps5 Hey there, sorry that you had not received a response on the pulse rifle. If you are still playing the game, you can try the following and see if they help out.
I did see players on the new game + having this same issue here
If you are not on that if you can load a previous save, save it as a new save file, reboot the game and load it manually into the new save and test it out. This way you don't lose any progress.
This could also be a corrupted update or save too as not everyone is having the same issue. The following should help with that too.
