GAC fight unable to use attacks/had to force close game when timer went to 0. PC

I was in a Grand arena round using SLKR with DSRey against a Jabba team. I nearly finished the match. When SLKR ult ended/Krrstan came back, it didn't let me take another turn. The game still ran and the timer went down to 0 and stayed at 0 until I was forced out of the game. It ended up costing the attack and took 0 progress from the fight. My internet never went out (I was in a discord call the whole time). It was immediately as SLKR ult came to an end. But this has very likely cost me the Arena phase as that was a GL fight that was lost (can see it would have been a guaranteed win) and I don't know that I have other counters. Ally code is 377447367. Not sure if it's some bug with SLKR or if there is a fix when this happens in GA.
