unity version download error
Hi. when I tried to download the newest non beta version of unity 2021.2, selected to install no addons on the second step, since I don't need anything else, clicked download and it displayed a message: "not enough space on the disc", or something like that (note: on that disc, I have currently almost 300Gb free, so there is no way that is the problem). I tried the 2019 version, since I already have 2021.1, and the same message showed up. then I tried the 2020 LTS, and the same happened. only the 2018 version was able to download. I know this isn't code related or something like that, but I tried everything: reinstalling unity hub, freeing up more space... I really do not know what to do. please help if anyone has the answer or some kind of usefull info, LMK...
