We have opened a beta branch with a build that potentially fixes the issue when a player cannot see sessions without Epic Games account linked or cannot open a server/connect to someone after launching the game + fix for the opening the browser tab with Epic Games authorization (this should not happen anymore). We invite everyone who experience such problems to check this beta and share your feedback.
Access code: 2NSk6jx4UUYndAju
How to switch to the beta branch: right-click on the game in the library > select "Properties" > choose the "Betas" tab > enter the code in the field and click "Check code" > after that, testbranch will appear in the list, select this branch > the game will update.
You can switch back by selecting "None" using the same method.
If you still face theses issues in the default Steam version and you have some free time, please try launching the beta branch - If the problem with opening the Epic Games tab persists, please write about it in the comments. If the issue is not relevant, try creating a session or connecting to open ones (there may not be any or there may be few, as this is a beta branch).
Please leave feedback on this iteration of the test in the comments below
