403 mean "forbiden", maybe you enter a wrong API key.

Please go to "Translate > Translate Engine Settings" :

And enter the API key for "Deepl" or, for other engine, enter required infos.

Similar issue,

(I filled my own email tho)

Language: From Simplified Chinese to Traditional Chinese
When attempt to "Translate selected",

it says,
[ value cannot be null. Parameter name: text]

Unfortunately, it's working on my computer with same settings than yours...

You can check on logs that are located on "C:\Users[User]\AppData\Roaming\Notepad++\plugins\logs\Translate\xxx.log" to find the cause.

It has the same issue no matter I fill my email or not. Editing XML file in UTF-8.

Will check later on another machine

The problem seems to be encoding conversion.
On original NPPTranslate plugin, it convert ISO-1252 to UTF-8 on function getSelectedText() :

Main.cs:225

                Util.writeInfoLog("Selected text range: " + selected);

                logEncodingInfo();

                Encoding w1252 = Encoding.GetEncoding(1252);
                string converted = Encoding.UTF8.GetString(w1252.GetBytes(selected));

                Util.writeInfoLog("Final selected text after conversion: " + converted);

And in your case it's already UTF-8, so conversion failed, and passed string to translate engine is "??????????" and that cause the error.

Tested again on another document in UTF-8 encoding, Chinese(Simplified)->Chinese(Traditinal).
No error pops up but only ??????.

I suspect it encounter issues as Chinese Characters isn't a part of w1252?
