crossposting this as another confirmation of this problem.
I can confirm the problem occurred to me as well in build 14332 and persists on build 14342, released today.
Fault seems to be ntdll.dll as mentioned by other posters.
Thanks. Added this info to OP.
Any news so far on this problem?
Well… you can try to complain to Microsoft about this one and hope they’ll fix this compatibility issue eventually.
Already have the feedback about this. But don’t know the time Microsoft will uses to fix it.
I’ve been voting up Tree of Savior related issues in the Insider Feedback Hub but no progress so far it seems 
HI i confirm 14342 to be broken tried to fix it for 6 hours to no avail ntdll.dll is the cause and more people should know before wasting time like i did heh : ).
Build 14328 for Windows 10 confirmed to work with TOS
So my idea is stay on 14328 until next stable build comes out , but i doubt it will be sooner than a month time .
IMC could at least release an update to overcome this situation, or at least an explanation of what is going on.
Now fast ring got a cumulative update. No fix.
Knowing that it is ntdll.dll doesn’t help a whole lot, it is responsible for a very large portion of Windows: https://en.wikipedia.org/wiki/Native_API. I also see a file StackDump_Client_tos[date/time].txt in the release directory with the following error:
Error Type : C0000005SymInitialize() fail : error(0)
I also had issue with the latest IPs and had to roll back to 14328
Yeah, same as me C0000005
i realized today too that i had this problem. will report this one too on the feedback hub of windows
Anyone update to 14352? Does it fix this bug? I still have to wait some time to get an update.
As i rolled back to previous version i will have to wait for when ISO files become available because my system wont receive update from Microsoft.
Yeap, 14352 seems fixed the issue. I can play the game again! ^^
I still not get an update 
Thanks for letting us know. 
I can confirm this, fixed in 14352.
