I tried to use VPN and PowerShell, I tried to turn off the antivirus, I tried to change Java versions, but nothing helped. I also tried to use the installer of another version, for example 1.0.2, or 1.0.1, but they crashed too. My internet is fine and I'm not sure if Fabric's servers are to blame for this, because I've been having this problem for 4 days now. The strangest thing is that I tried to use the installer on another computer in my room and it worked. I installed Fabric 1.21.5 on it and transferred these files to my computer. Then I had to download Fabric 1.21.1 and I decided to do the same. But literally 2 hours later, the installer stopped working on the second computer too, although nothing has changed. Here is the latest crash report:
Fabric installer 1.0.3 has crashed!
