Using the new launcher, and launching Minecraft 1.12.2, the game will start up fine as long as it wasn't in full screen mode the last time it was used. Once i try to switch it to full screen, however, whether through the F11 key or through the options menu, the game immediately crashes. The following appears in the log:
21:15:17 bib Couldn't toggle fullscreen org.lwjgl.LWJGLException: Failed to set display mode (-2). at

That bug is reported to have been fixed in a much earlier version back in 2014.
As much as I can tell, the issue is with the default arguments that the launcher is installing on new downloads of Minecraft versions and those who have not had their JVM Argument defaults changed.
Go into Launch Options
Click the version you want to edit
Click the ticker next to JVM Arguments
Click Save and see if that helps. If not you can go back and undo the ticker to set back to default. The new bug appears to be that of the Launcher, not the actual game.
Changing my screen resolution seems to have solved the issue.
i was running at 1768 x 992, which made the text on my screen a bit more readable. Now that I've changed to 1920 x 1080 (which Windows 10 has marked as "recommended"), I was able to take Minecraft into full screen mode using the F11 key with no adverse repercussions.
I'm using an HDMI cable to connect my system to an HD TV, which is why my text is not as sharp as it would be with a standard monitor.
I don't know why I didn't try this ages ago!
If anyone has any info regarding why the resolution makes a difference, I'd be most interested to hear it.
i changed the resolution to a 1280x720 then back to a higher setting and windows told me it has some features blocked by a firewall i gave minecraft access no issues now nothing else installed nothing no work arounds other then that just a firewall issue

I have created a DxDiag report. The link to it is: https://pastebin.com/HbJtZJca
Thank you.

If the field reads:
-Xmx1G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=16M
Change the field from that to:
-Xmx1G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

No, the bug was fixed in the snapshots and not released to the public yet.
