Implementation

Reproduction Steps
Hey!
I've searched and nothing came up as this weird error.
Randomly today, when trying to debug a program and building the application with CefSharp assemblies...
when it ran the program crashed.
Running OLD already WORKING programs of mine output the same error afterwards!
Since that all my other programs of mine with CefSharp assemblies were also crashing on startup.
The general event log as follows:
I was trying to reproduce what I did wrong here, but I didn't changed anything with any of my programs.
Searching online came up with debug.log CefSettings.root_cache_path warning.
I thought, maybe because all my programs don't use SET CefSettings.root_cache_path setting, they all read from the same DEFAULT path.
in C:\Users\username\AppData\Local\CEF
So, maybe this is the problem...
I renamed the folder to CEF-old and tried to run again the program, WORKED!
What gives?
Can you somewhat get the faulting code from the offset 0x00000000014b5f79 ??
with version 144.0.12 the offset is 0x0000000001433ae8 btw.
Let me know because this could help others!
