"Access to the path is denied" or "An error occurred trying to start process" regarding RobloxPlayerBeta.exe

This issue is relevant to you if your error message looks something like this:

System.ComponentModel.Win32Exception: An error occurred trying to start process 'C:\Users\xxxx\AppData\Local\Bloxstrap\Versions\xxxx\RobloxPlayerBeta.exe' with working directory 'xxxx'. Access is denied.

or

System.UnauthorizedAccessException: Access to the path 'C:\Users\xxxx\AppData\Local\Bloxstrap\Versions\xxxx\RobloxPlayerBeta.exe' is denied.

Recently, for some unknown reason, certain antiviruses have began falsely detecting Bloxstrap downloading Roblox as being malicious, resulting in the antivirus not allowing Bloxstrap to launch Roblox.

To fix this, you simply need to add Bloxstrap's installation folder as an exception. If you don't know how to do that, look up how to do it for your specific antivirus make.
