Hi, I would check to see if the Glasswire Control Service is still running under services despite the application front-end crash that you have shown from the Application Log. If the control services is still running it is likely all rule processing is still active and being followed as my understanding is that the Control Service is what does all the firewall processing and collection of information. The Glasswire.exe connects to this service to provide the GUI interface to this control service.
Of course this does not resolve the issue of the front-end application component crashing. It is possible that a Glasswire code dependency on another component such as Visual C++ Redistributables or .Net versions is possible corrupt and need reinstall. Glasswire Developers should be able to advise what dependencies their software has.
You may also be able to try and narrow down the issue if you have technical skills by using tools such as SysInternals Process Monitor which may give an indication of missing files, registry entries, or other calls from the program that may be causing the program to fault.
