Minecraft hangs when loading and gives no feedback

I downloaded Minecraft Java Edition on my laptop. Until recently, it worked just fine. From 27. respectively 28. 02. it hangs when loading just before it's done and doesn't give any feedback. So I can't get to the main menu. Affected are the versions from 1. 14 upwards. Everything underneath works. I've already uninstalled and reinstalled minecraft, I've deleted the minecraft folder from my laptop, I've already set minecraft to access more memory and it's all done nothing. I am in desperate need of help and would appreciate a quick reply. Thank you very much in advance
