launcher failing

The launcher will not complete. This has been going on for about a month now. When I launch the game it loads on the first page but when I get to the pop up it will not finish loading. Then, it tells me that it has sent a crash report. I have tried updating my java, as this is a java edition. I have tried changing the compatibility mode. No success. I have tried uninstalling and deleting the game from my computer. Then, when I reinstall it, I have the same problem.
It will not let me attach the screenshots of the issue.
Also this is on the 1.15.2 version. I do not know what those other versions are.
