Same here. No mods installed on the moment.
Only error from the log is following:

[Error: 2020-04-17 17:33:21.1696255: GameController.cpp(166)] Missing 'url' on libraries[*].artifact (should be string) in library net.minecraftforge:forge:1.15.2-31.1.0

It looks that Forge devs commented out or have deleted url path for certain libraries from the launcher. or even forgot to setup variable as a string.

please fix this asap.
