What is this vertical white line crossing all my tracks??

What is this dotted vertical white line going through my tracks.

That showed up and suddenly I can not drag clips or drag effects to clips. 

What did I do?

[Ann Bens]

this appears when dragging a clip while holding down CTRL.

CTRL button stuck?

Reboot program.

Is it for a purpose or is this just another of those 9000 things that freezes premier so you have to restart everything. 
I spend more time restarting the program than actually using it.

Is it for a purpose...

By @Bryan233923755bq7

Yes, the purpose is to indicate that the clip you drop into the timeline will do an insert edit rather than the default owerwrite edit. Since it just showed up and stop you from using Premiere Pro i would start with closing Premiere Pro and then launcch it while having the Shift-key pressed down. This will bring up a dialog that let´s you reset the preferences. Resetting preferences often solve issues like this, when odd things just happen.

If the app freezez often it can be due to the computer itself and/or the kind of media you are editing. If you need help with that, post all details.

As Ann said before: do you see this line all the time? Have you tried resetting Prefs as Averdahl suggested? Please describe what's happening exactly on your side, it would be better if you show us a screen recording of the problem.

Honestly, premier freezes on me about once per hour of editing and it takes all of the known forms, Program screen going plack, play head not moving, White Screen and shutting down. I have been using it for 5 years and the program freezing and locking up every hour is completely normal now that I just edit for 10 min, shut it down and restaart it as part of my process. I am just editing Goro footage on what I consider to be a pretty good PC. 

If you google "Premier freezing" you see this program is so buggy I cannot believe we are renting it for what Adobe charges. I am teaching myself 2 other editors right now because they dont have any of the bugs Premier has. It is just that premier is simple to use. but it is the buggiest program I have worked with and I have been a software engineer for 25 years. I am not a novice. 

I am not doing anything massive. Just 2-3 tracks of 4k video most clips are about 15 min long. 
Today it froze onmt multiple times just showing that green screen with all the different languages and wouldn't respond. 

I have tried permier, beta, and many versions back over the last few years and it is just unstable for me. 
This is the 2nd PC I have used with it. The prior had the same issues with freezing and locking up.

[Bryan233923755bq7]

Number 1 problem that I can create about 75% of the time. 

Simply dragging a clip from windows explorer to the timeline and the program crashes. I have to end task and start it again.

Wow, this is sad. PPro is really stable on my side, even with my really old GPU (1080 TI).

Couple tips: try to install the latest studio driver of your GPU, and disable all the plugins: some of the plugins could crash PPro all the time, even if you don't use them in your projects.

That´s probably the issue, the media you use. Both are very, very hard compressed and are known for causing issues like yours.

As a test, try to transcode the files for the next project to Apple ProRes and edit with those files instead. Or even better, use a proxy workflow but use Apple ProRes as the codec.
