BadImageFormatException is thrown after a few days

I've gone through several posts about BadImageFormatException but I couldn't find answer to my situation.
I've a C# project that uses few 3rd party DLLs. The project's runtime is .NET Framework 4.8. I build the project using "Any CPU" configuration in VS 2022. An installer is built and the software is distributed through the installer.
On the end user's Windows 10 x64 machine, the software runs fine for a few days. After that suddenly the software stops launching. When tried to launch, Windows generates the following event logs:
Application: <application name>.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.BadImageFormatException
and

Surprisingly, replacing the .exe file with the original .exe file solves the problem and makes the software starts again.
What could be the possible reason for this? How to fix it?
I've checked all of the 3rd party DLLs with file command that all of them are built as 32 bit DLL.

ASP .NET MVC Application crashes randomly

I have a web site developed in ASP .NET MVC 5. It was working normally during last 9 month but since the web site got many active users (about 200 concurrent) it started to crash randomly in every 25~90 min. The strange part is that there is no exception in my log and the only exception that I could find is this in my event log:
Faulting application name: w3wp.exe, version: 8.5.9600.16384, time

Can any body explain me why it's happening and I can get more detail about exception and it's possible resolutions?
Update 1:
I found two hot fixes (https://support.microsoft.com/en-us/kb/2679415 and https://support.microsoft.com/en-us/kb/2640103 in Microsoft site which seems that is the case. One of them is not applicable for Windows 2012 :| the other one is not accessible to public. My emails to Microsoft site is also not answered!
Update 2:
Finally after hours and hours of research and code review I found cause of problem. In my code I was loading a DbSet from my Entity Framework db context. The records of database in that table was huge and because of this my app was crashing. And because I also had app pre initialization configured in IIS after crash again it started to load that DbSet again and here was a loop of crashing and crashing!

NReco PDFGenerator issue

I've been using this tool for about a week, and now, today, it just stopped working. I've reverted the rest of my code back to the previous state and I keep getting the same error.
All that I'm getting from the Exception that is thrown is:
An exception of type 'System.Exception' occurred in NReco.PdfGenerator.dll but was not handled in user code
Additional information: Cannot generate PDF: (exit code: -1073740791)
From the Windows Event Log:

Any ideas what could be causing this?

The reason of this error is not in your code: it seems something changed in your environment and wkhtmltopdf.exe stops working because of missed VC++ 2013 runtime libraries (required for latest v.0.12.2.1).
You can download and install them from Windows Downloads: Visual C++ Redistributable Packages for Visual Studio 2013
PdfGenerator embeds x86 build of wkhtmltopdf and you may install only x86-version of redistributable package ( vcredist_x86.exe ).
--- update ---
For latest wkhtmltopdf 0.12.4 VC++ 2015 runtime libs are needed.

application.exe.config file issue when installing on a clean machine

I have created an installer project in WPF. when I run the application on my computer, it works fine. I set a minimum requirement for the .net framework 4.5. But if I run the application on another machine (with newly installed windows 7), the application crashes.
Below is event viewer log:

Exception Info: System.IO.FileNotFoundException
Stack:

I tried to create "Window event log" inside Main() try-catch method, but the application was not able to reach to that point.
When I send myinstaller.config.exe file with project exe file in the new installed machine, then it shows error. That the application does not meet requirement.
In my machine myinstaller.config.exe is not requirement, even after I uninstall framework 4.5 and 4.0.

Unhandled exception for the component "MultiScaleImage" of "Silverlight 5"

I am developing a web application based on "Silverlight 5".
I found a blocking bug related to the component "MultiScaleImage" that happens after a unpredictable (sometimes it takes hours, sometimes minutes) number of zooms of the image.
When the issue occurs the following messages are shown:

Internet Explorer 11: Internet Explorer has stopped working.
The test has been done with Win7+SP1 with IE11 and IE8.
This bug is preventing me from releasing the application and deploying it to the customer servers.
I can't believe there's no way to solve it nor a valid workaround.
