Studio dragger emitting errors

I was testing something in studio today when the dragger got very angry at me.

Any time I moved my mouse within the studio window, it spat out more errors.

After this happened, I was unable to select the select tool & drag parts around.

I ran into this in a non-team create place (the place wasn’t tied to any game on-site). This happened when I did a quick (very quick!) test with run mode (green arrow), then hit the stop button.

When I press the “run” button again, I can use the select tool, but hitting “stop” brings me back to the same error.

This should be fixed now, let me know if you still have a problem.

as soon as I joined studio errors on the dragger popped up.

Reverting a change right now, one sec.

Edit: Should be fixed now if you restart studio.

I am experiencing this issue too.

Appears to be fixed now after restarting studio.

Currently getting a similar issue in my game.

tnavarts · May 27, 2021, 9:12pm

What studio version are you on? (check it using the File → About dialogue)

FelixProfit · May 28, 2021, 4:23am

Here. This error occurs when testing with the mobile emulator.

This is the player list throwing errors, not the studio draggers.
