Sounds like a virus/malware infection to me. If neem's suggestion of re-installing Chrome doesn't work I suggest you scan for viruses/spyware viruses. First use whatever AV program you currently have installed (Windows Defender (WD), Norton, Avast, etc.) and scan/remove all found viruses. Next, visit
malwarebytes.org and download the free antispyware program
MALWAREBYTES. Run Malwarebytes and scan/remove all found spyware viruses. Reboot your PC and retest. If Chrome begins working again, you simply had a Chrome virus
(they are very popular as Chrome is the #1 browser these days on Windows computers; so it is the #1 target for them!), and you're all set to go!
Best,
