Changing Settings Causes Crash

[Gobiff87]

When I attempt to change any settings the app crashes. If I make only 1 change at a time and restart the app, sometimes it will take but again, usually crashes. I cannot add more extensions etc... wanted to add the newer image ext. like webp and jfif. I attempted to locate a config file but could not. I thought maybe I could edit some things in there.

I am using the latest updates for windows 10 pro, I have a z790 godlike mb, 64gb ram, RTX 4090 blah blah and so on.
I am in no way any type of programmer, however, I've learned I cannot trust chatgpt. but it kinda does help sometimes. here is what it told me after I shared the crash logs with it:
Based on the provided crash log, the crash is occurring in the application "DownZemAll.exe" and the fault module responsible for the crash is "Qt6Core.dll". Here are some relevant details from the log:

Application Name: DownZemAll.exe

Fault Module Name: Qt6Core.dll
Fault Module Version: 6.3.1.0
Exception Code: c0000005 (Access violation)
Exception Offset: 0000000000523410
The crash is marked as "IsFatal=1," indicating that it is a critical issue. The exception code "c0000005" typically refers to a memory access violation, which means the application is attempting to access memory that it doesn't have permission to access.
