I reinstalled my Minecraft Launcher today and noticed that I can no longer open the Minecraft Launcher while playing the Java Edition.

Clicking on the Minecraft Launcher while in the Java Editon just jumps you back into the game instead of launching the Launcher.

This is only with the Java version. When I play with Bedrock, I can open the launcher as usual.

The only way to fix this is to stop the Minecraft Launcher task in Task Manager. Maybe this is the problem as the launcher is not supposed to be in the background processes? Bedrock does not put the launcher in the background processes.
