dop2000 Incognito mode does nothing and is not feasible because the issue is that if I clear my cache, the problem goes away even in normal mode, but I have to reset C3 settings all over again, and there is no easy way of doing it, like importing settings, for example, like in a json file, that would solve my problem, but it doesn't exist. Desktop build also does nothing. I use no antivirus nor vpn. Also, as I mentioned, the problem occurred even on clean installations of both Edge and Chrome.
I did use console log to check for errors and it churned out a significant amount of information, as seen in my first opened issue. Warnings and errors all around, but also nothing was done about it.
EDIT: Also, I don't agree with you nor Ashley that screenshots are not helpful. You can clearly see a decent amount of information on my screenshots for the first issue. I just didn't had the energy anymore on the second one (which is the same issue).
simstratic I've cleared my cache many times and it always happens again and again. Chrome started doing this for me some months ago, but Edge only started doing it when 216 launched, which makes me think there's something related to versioning. I did not update to 216 on the fly, but on my first login after it launched, there the bug was. I have pretty decent space on my drive and I do use beta versions.
On a side note, I always open the page through a bookmark that I manually edit the number version to keep using it. I really can't think of anything else.
But as I said. I appreciate the help, but I guess this is it.
