How to connect to a Selenium server through RSelenium?

Question

I'm trying to learn how to use the RSelenium package, but I haven't even been able to connect to a server yet. My code is as simple as:

library(RSelenium)
rs_driver <- rsDriver()
rs_driver

The error message I get is:

[1] "Connecting to remote server"
Could not open chrome browser.
Client error message:
Undefined error in httr call. httr output: Failed to connect to localhost port 4567: Connection refused
Check server log for further details.
$client
[1] "No sessionInfo. Client browser is mostly likely not opened."

$server
PROCESS 'file413018516402.bat', finished.
Warning message:
In rsDriver() : Could not determine server status.

I already tried:

1. Updating Java, Chrome, RStudio, and both netstat and RSelenium.
2. Several different specifications for rsDriver() arguments, varying:
   • The browser. For Chrome, I also tried different versions, varying chromever.
   • Setting port manually, or by using free_port() from netstat.
3. Turning off the Windows Defender Firewall for RStudio (though I'm not completely sure if that's necessary and if I did this properly).

Despite having come across some related questions (as listed below), either they remain unsolved or the suggested solutions weren't successfully implemented by me.

• RSelenium browser not opening
• Can't use RSelenium package, function rsDriver() says can't connect to browser
• RSelenium won't connect to remote server

I'd really appreciate any help :)

Deleting "LICENSE.chromedriver" (Ric Villalba's suggestion) solved my problem.
