[SOLVED] Can't login on Edge anymore! (Login and Sync issue)

UPDATE 10 APRIL:

Finally got a hold on https://support.microsoft.com/, initiated a live chat with support, and they had to install Install Quick Assist (Install Quick Assist - Microsoft Support) and they had to enter my PC and check what was wrong. They had no idea what was happening at the time (this all happened a few weeks ago - sorry for the late reply ut I had a lot of work delayed due to this error) and reinstalled Windows = issue solved.

The following day however, windows asked me to update again and the issue returned ahahahaha but I removed it, and then the following system updates didn't carry that sign in issue anymore.

Thank you all for your help and support during these VERY STRESSFUL DAYS! Hope the issue got solved for everyone!

UPDATE 25TH - 4:52 GMT:

- Run every possible workaround thanks to comments on my Microsoft Community thread and here (Tech) (Thank you everyone!)

- Can't get pass the edge login pop-up => can't sync and have access to workspaces;

- Already reported twice on Alt + Shift + I (with screen recording video and photos);
- No 3rd party antivirus issue;

- Some people on the Community post were able to surpass this by uninstalling KB5035853 - but I don't have it;

- Using Windows 10 Home version 22H2, with Edge version: 123.0.2420.53 (64 bits) [also tried on Edge Beta version: 123.0.2420.53, but uninstalled it for now]

UPDATE: 22nd OF MARCH:
There was already some suggestions left here (Can't login on Edge anymore! (Sync issue) - Microsoft Community) but it didn't work. Anyone? Please?

_______ original message posted on 20th March _______ 

Already hit restore on windows' applications and restarted my pc, but every time I open Microsoft Edge now, on the top right corner it says my account is not logged in. And when I try to do it, the pop-up window says it's loading and then just turns to all white.

Anyone can help me please? Don't want to lose my favourites, passwords and workspaces ;_;

1) already deleted all cookies
2) already confirmed if it was an issue with the Wi-Fi

3) already hit «repair» twice on the program

4) already tried to add a new account (didn't work cause the issue with the popup to login is the same)
5) already disabled all extensions and tried to login again after that
6) my account is not blocked - in fact I can login on Microsoft with it on my phone and website (otherwise I wouldn't be able to post this question). The issue is only with logging in on the Edge browser.

7) already deleted and reinstalled Edge.

And yes, I restarted my pc every time I tried something.

What else can I do? I need to access my Edge Workspaces!
