Client crash on changing ascendency

I changed my sorceress ascendency 2 time in the first Trial of Sekhemas.

I changed from Stormweaver to Chronomancer, after confirming ascendency change before the animation the client crashed.

Later I did the first trial again to change back from Chronomancer to Stormweaver and the same occured, after clicking on confirm ascedency change, before the animation the client crashed.

I was playing on steam if that is important.
