Full stuck outside Viper Napuatzi fight

(ignore the gamma deep fry it's just HDR looking weird in the screenshot)

I dodge-rolled as the barrier guards advanced, clipped through them and got stuck outside, and I'm now full bricked.

I can't portal in a boss fight.

I can't teleport to a party member, and after painstakingly walking the entire map to my boss fight (because they couldn't use the checkpoint), they died trying to kill her, so they could not rejoin without me also dying or reviving them. But, Viper herself cannot actually hit or damage me, and I cannot hit or damage her back.

Re-logging, swapping to another character (both in standard and in league) did not work, because I just reconnect to the same character in the same position due to the crash/disconnect protection.

I've just alt-F4'd and will wait for the portals to hopefully close.
