    Yeah I get this start-up crashing too. Problem solved when I rename the last scene in use before I open up the project. I have Unity 5.5.0f3 and use text mesh pro.

    Is there any ETA on when this bug will be looked at. It does not happen all the time but when it does it takes a good chunk of a day to get back to productivity. An update would be appreciated.

    This happens sometimes when building asset bundles as well. The problem went away after rebuilding asset bundles.

    Have the same issue: sharedassets0.assets.resS couldn't be found. To get around this issue I've set the font to dynamic - but just a workaround for the time being.

    Got the same Problem: sharedassets0.assets.resS couldn't be found and therefore opening the file failed.

    Same problem at Unity 5.5.0f3. When do you plan to solve this?

    I get the same crash and errors messages, but I'm not using TextMesh Pro. It also happens when building the player.

    Created a video to show the steps to reproduce this issue. As I explain, I believe this is related to Unity internally and momentarily losing reference to the material or texture embedded as a sub asset of a main asset which happens to be the structure of Unity's fonts as well as TextMesh Pro's Font Assets.

    Besides showing how to reproduce the issue, the video covers how to get around this new bug and more importantly how to recover from it when corruption of a Font Asset / Material occurs.

    Hopefully this video will help Unity isolate and solve this issue quickly and more importantly show users how to recover from the affects of this bug and how to avoid it as well.

    If any TextMesh Pro users are affected by this where after following the steps shown in the video you are still able to overcome the issue, by all means reach out to me via email as I will most certainly be available to assist in any way that I can.
