I got interested in opera GX but I really encountered a lot of problems.

my first problem is to download it, when you are on the official site you cant download the 64-bit version, even if you clicked ''64-bit'', I ended up downloading it from a third-party website.

the second problem and the Biggest problem is I can't download any extensions because I can't even access the https://addons.opera.com website.

after long research, I found out it only works if I use a VPN, which is a shame.
Well, the third problem is I can't even use the inbuild VPN of the browser lol. so I am stuck.

how did I know that it needs a VPN to work? I used a VPN on my phone then visited the website and it worked.

thank you please there any solution.
