Windows 10: Shell launcher stopped working after Windows update

After the latest Windows update, KB5048652, Shell Launcher keeps crashing on all our Windows 10 LTSC Devices. We have tried multiple applications within the shell launcher configuration but the same issue keeps happening. Hereby the event logging from application logs: Faulting application name: customshellhost.exe, version: 10.0.19041.5247, time stamp: 0x22e6ff08 Faulting module name: customshellhost.exe, version: 10.0.19041.5247, time stamp: 0x22e6ff08 Exception code: 0xc0000005 Fault offset: 0x000000000003f4ce Faulting process id: 0x24b4 Faulting application start time: 0x01db4cad6ae2afb7

Windows Shell launcher failing to start application after update

Good afternoon all,

I have an application that is launched by the Windows shell launcher (V1), this is been loading for well over a year on Windows 10 Enterprise LTSC version 21H2.
Recently machines have been updated to OS Build 19044.3208, since that date our application has failed to be started by the Shell launcher, neither V1 or V2.

I have changed the Shell launcher to start CMD which starts as expected, so Im sure the Shell launcher configuration itself is still ok. I have not been able to track down any log entries in Event viewer to help. The application is signed with an EV code and is passing verification in signtool.exe.

Where else in the system can I look for logs/information as to why the application is not loading?

Thanks in advance

Googling variations of the title I used in this post was not fruitful - I found nobody who had a similar problem so far. Restarting the computer does not fix the issue. Any tips on the appropriate steps to diagnose or fix this are much appreciated.
