Hi, everyone,

I am having a problem with a script that was previously running without issues. The scripts starts, runs up to the point where the window is shown, then stops without issuing any error message. I have tried to locate the problem by removing components in a somewhat haphazard way and found out that the crash occurred in “vk.pyo_init” (by commenting this line). However, without an error message I am lost as to what may be causing the issue.

We did not change the code in any way. As far as I know, the only change that was done to the computer was that it was plugged to the internet cable. I checked for updates in Windows, and there was one security intelligence update to Windows Defender Antivirus. I tried disabling Windows Defender completely using the registry, but this did not work.

Does someone have any hint as to what the problem could be?

Here is the section where I use “vk.pyo_init”:
