If I equip two crossbows the game breaks

Now that I'm a bit into the endgame I've bought a second crossbow (one for nades, this one for galvanic shards) to spec into lightning dmg nodes.

Re-specced my passive nodes and my weapon set skills (like, selecting the option to use galvanic shards on my weapon II only), but when I fire it, my game breaks:

Can't go into the endgame map portal, can't select a waypoint, can't talk to NPCs, and at one point the game crashed.

First time using the forums, I've used the /bug command and it's given me this reference number 1.180.154.455

I think I fixed it but it's unstable cause the game just crashed so it might crash again in 5 mins. I put every single piece of gear manually again in their slots, put the gem again in its slot and it works.

It feels like the game thinks you don't have some sort of requirement like dex or something and doesn't allow you to use that skill. I have a duplicate skill "basic shot" and a duplicate skill "load crossbow shot", the game was even shooting basic shots with the galvanic shards icon lmao

There was another guy talking about it https://www.pathofexile.com/forum/view-thread/3750814
