Problem with Selenium WebDriver Connection


I’m facing problem with WebDriver connection, Functional and SUT systems are connected through RDP and when I tried to connect the WebDriver I’m getting an error like "Response code 500 received from Selenium Server. {“error”: “unknown error”, “message”: “unknown error: cannot find Chrome binary”}.
So due to this issue I’m not able to run any scripts but previously it was working fine.

Could anyone please let me know how to resolve this problem?

Please find the below attachments for reference.

Any help will be appreciated.

Thanks in advance!
