Freeze on Colonnade Map Boss

When i tried to do the colonnade map boss the game froze completly in the second phase, when he went to full energy shield. The game is running still judging from the task manager and its activity but nothing its completly frozen on the screen. I also checked if it was only a bug with the map mods but it also happend exactly the same with another colonnade map with different mods. If it has anything to do with the bug i was running the map with a summoner zombies/spectres. Im running the game with the settings:
- DirectX 9Ex
- Windowed Fullscreen
- Shadow Quality Off
- Antialiasing Quality Off
- Texture Quality Medium
- Texture Filtering 2x Anisotropic Filtering
- No Post Processing
- No Screen Shake
- Eninge Multithreading Enabled
- VSync Off
- Prozessor: Intel Core(TM) i5-6200U 2,4GHZ
- The GPU is some shitty AMD

Would be nice if this would/could be fixed somehow else i cant get my shapers ORB :(

Thanks in Advance

Edit: Tried it wiht DX 9 and it still happened :(
Also Tried it with DX 11 and it still happened :.(

As an addition i had no problem prior with this boss in beta and in the last race
i want my 6c back for the 3 maps for the testing Kappa

encountering the same problem.
it worked yesterday, today i cannot finish the boss due to crashes :/

:edit:
Dx11
Intel Xeon
Geforce 750ti
win7

:edit2:
dx9ex crashed aswell
dx9 allowed me to finish the map \o/


:edit3:

same crash on vault boss now, but switchign DX versions doesnt help :(
you guys owe me a harbinger orb, a t11 map, a vaal orb and 30% exp to lvl 89 :/

Crashing on this boss now as well. I'm pretty sure this was caused by one of the recent patches, since I did not crash when I cleared the map several times 2-3 days ago.

Just crashed also :/

Did Colonnade after the new patch and it worked perfectly thanks Dev Team and Forum Team ;)

just crashed also.

Crashed, tried changing dx9 dx9 ex dx11 turned off various settings. Wasted all portals trying to get past the crash on the first teleport.

Killed a few players on the ladder as well already, https://clips.twitch.tv/HonestConcernedDonutWow, gating the shaper's orb behind a bugged map is pretty frustrating tbh.

I've run about 6-7 colonnade maps. It has only happened on two of them, not consecutive ones either. Can't remember the exact stage of the boss on the first crash, the second crashed a few seconds after he reengaged me from the first (I think) breakpoint.

Both times I froze again once I reentered the boss room the first time, but was able to continue the fight second time I logged back in the game.

A curious note on the map is that it partially reset the map (everything I had discovered prior to emptying my inventory stayed revealed).

DX11, windowed fullscreen using a GTX 960.

Crash yesterday and today, over 5-6 RIP
Glad i'm not playing in HC.
There is a serious problem in there, that occurs on the last phase with meteors.
