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:

Faulting application name: program.exe, version: 1.0.0.0, time stamp: 0xf76183d3
Faulting module name: libcef.dll, version: 143.0.9.0, time stamp: 0x691e395d
Exception code: 0x80000003
Fault offset: 0x00000000014b5f79
Faulting process id: 0x1248
Faulting application start time: 0x01dcdacf27a16c2a
Faulting application path: C:\temp\program.exe
Faulting module path: C:\temp\libcef.dll
Report Id: 2869397a-cc26-4042-adfe-8893b2567301
Faulting package full name:
Faulting package-relative application ID:

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!

Converted to discussion as crashes in libcef.dll are very rarely bugs that can be fixed directly in CefSharp.

Each application should have it's own unique root cache path. Using the default is not recommended. Other applications also maybe trying to use the same cache path and that'll be very problematic.

Not that I'm aware of.

Faulting module name: libcef.dll, version: 143.0.9.0, time stamp: 0x691e395d

Exceptions in libcef.dll are generally CEF/Chromium bugs.
