PTR Crashing on Enter World

With the latest update to the PTR ( a portion of players are experiencing hard crashes when loading into the world. The client launches and realm/character selection works but part way through the load bar after pressing Enter World they receive the following crash.

ERROR #0 (0x85100000) Assertion failure!

Program: C:\Program Files (x86)\World of Warcraft\_classic_ptr_\WowClassicT.exe
ProcessID: 920
ThreadID: 12788
File: D:\BuildServer\C\work\DedicatedCheckout\Storm\H\SStr.inl
Line: 74
Expr: string2

Here is one report ID from this crash - 578AE59E-62EB-4102-8F1E-F4093590ADB1

Notably the Scan and Repair function in the launcher also crashes when running, at ~19% we see “Whoops! Looks like something broke. Give it another shot.” Running this again does nothing.

I’ve deleted my WTF, all addons, fresh installed, updated drivers, and even tried on a separate device with completely different hardware.


Also getting the same issue
I have tried everything to try and get it working - no luck
My last option is to fresh-install windows which i want to avoid.



bump!! !!
