Hi Bhavya,
I'm Sumit, here to answer your query at the Microsoft Community.
Code 43 can point to a defective GPU.
Use DDU to remove the drivers and see if it helps.
Please see the Display driver troubleshooting below:
Remove the Display drivers completely and Install the newest copy of the driver, available from the OEM or the GPU maker. The steps for it are here:

Eventually, after Windows restarts, check for Windows updates, or download the display driver from the computer manufacturer.
Afterwards, the installation, see if your issue is resolved.
