I have the same issue since last modpack update and I am not using Overwolf. Is clearly something from the mods installed since it worked great before they made the update, but idk what. I have a ton of mods installed and it would be hard for me to do the good old trial-and-error way of finding the conflict, so I will just wait for an update from ProMod
Idk if you should bother with it, but I found this mod cool, here is the link to the official site: https://wgmods.net/2906/
Edit: If u ever consider adding that mode, add this aswell please, they are quite similar: https://wgmods.net/3335/
So, as usual, I use original WoTs icons, I have that ticked in the modpack but for some reason Im getting those icons instead. I attach a screenshot and the logs here.
UPDATE: No matter what icons I select, I am still getting those.

FINNALY after weeks I found out what was causing the bug for me... If you have a tank in your garage and you have 100% mark of exellence on it, for some reason, marks on gun extended mod wont let you enter the battle. The only solution is to deactivate the mod in-game before you wanna play with a tank that you have 100% marks so you wont have to restart the game at the battle loading screen. It must be a verry rare problem because soooo few people have tanks marked to 100% that nearly never appears. Anyways if any of you are pro players like me and have tanks with 100% marks now you know that this is causing the freeze at the battle loading screen.
Well, that didn't work. And I did some more tests and I discovered this bug happenes only in my E-50 , all the other tanks load just fine. I really don't know what could be, that is really strange.
