Minecraft launcher crashes upon clicking "play", has no known fix

I have recently installed Minecraft Java edition using an older account (account made maybe 2015-2017) but upon installation when I press the play button on the launcher it proceeds to state "finalising" before it crashes out giving the error input  "java.io.FileNotFoundException: C:\Users\ZADEN!! (Access is denied)". I have tried every fix I could find but to no avail, I have looked on the bug reports section but no answers have been given. please find affixed images containing my everlasting strain due to the launcher.
