Hi there and welcome
Can you please click start, type in
In the window that opens, click on Appdata at the top
Then click on Local
Then delete the folder Google
Once done, try to open Google Chrome and tell me if it now opens.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know the results please.
