Same issue here on Mac OS Ventura 13.0.

Working fine on 1.25.0

[ZeroBloodedge]

Same here on MacOS Ventura.

I apologize for the trouble you are going through.
This is addressed in #5444.

[filipw]

FWIW @dibarbet is empowered to release an update (or perhaps first a prerelease VISX package)

[stewartm83]

@filipw did they manage to release the patch?

for those who searching for a quick solution:

worked for me, thanks a lot!

After installing you'll want to disable the automatic updates on the c# extension until the issue is solved. Otherwise the problem will come back

[sq5]

downgraded to 1.25 to fix this problem

[DMaxwell02]

downgraded to 1.25 also fixed my problem

[EnderDremurr]

downgrade helped

We will be looking at doing an emergency 1.25.2 release to address. Locking this thread for now to avoid burying information.

[dibarbet]

1.25.2 has been released. Please file a new issue if you still encounter issues. Thanks all!

On MacOS Ventura it worked again when I installed .Net (ARM Version) instead of x64.
Thanks for the tip @Hamedkabir

[psaraviaq]

Hope it'll work for Windows too in future versions ...
