Hello I am running into this issue recently as well.
Here is a run down, Last night I had to reinstall windows 11 due to my PC getting a recent windows update that caused my PC to go into a Boot Loop where it gets to the login screen or desktop before it totally blue screens and repeats this.
I got to the windows recovery screen and had no choice but to reinstall windows but I used the option to keep all my files but lose the apps and files related to those apps that did not come with the PC.
After an hour of reinstalling windows and recovering all my apps and such I had to reinstall the epic games launcher I went to your website and I downloaded the installer.
Of course fate would have it against me and I get greeted with the message after installing the launcher “multiple crashes detected” I can’t keep running into this EpicGames please find me a solution I tired contacting Microsoft and only got a copy/paste PR response and then I got users telling me to do stuff and that stuff failed I don’t want to keep going through this I am in your creator program so there has to be a 100% fix for this and I am not reinstalling windows 11 again and NO I can’t downgrade my PC came with windows 11 installed and No I am not calling or Emailing my PC’s manufacturer because they won’t know what to do either I tried it so i know.
