The computer has rebooted from a bugcheck. In bugcheck we found The win32kfull.sys file is associated with the KERNEL_MODE_HEAP_CORRUPTION bug check (0x0000013A), which indicates corruption in the kernel-mode heap. This often points to a problem with a device driver. It generally points to problems with drivers, corrupt system files, or hardware issues. File system corruption can cause this issue i.e. This is an Operating system level file Win32kfull file. I have found out this with the dump file present in the logs by dump file analysis. I have checked the old log where on july 8 same driver as caused the problem

Since you've identified that the win32kfull.sys file is associated with this bug check and that the same driver caused a problem previously, here are some steps you can take for further troubleshooting:
- Go to the manufacturer's website for your hardware (graphics card, network adapter, etc.) and download the latest drivers. You can also use Device Manager to check for updates.
- Run the System File Checker to repair any corrupted files. Open Command Prompt as an administrator and run this command -
sfc /scannowand then restart your computer after the scan completes. - You can also try use the Deployment Imaging Service and Management Tool (DISM):
This command also will help you to repair it.DISM /Online /Cleanup-Image /RestoreHealth - Use the Check Disk utility cmd to scan for file system errors -
chkdsk /f /r
Hope this helps!
Please Let me know if you have any queries.
