Hey Satheesh,

Would you be able to send us this asset that is crashing/no longer opening?

Yes sure. I have attached it with this post. I have now loaded an older backup from the autosave and now i can open it.

Hey Satheesh,

We were able to repro this crash in the 4.1.1 released version, but it does not repro for us (the asset opens) in our 4.2 build we are testing internally. We just posted a 4.2 Preview build to GitHub this morning if you’d like to pull down that build and compile to try to open your asset (mind you, that build still considered unstable).

Great to hear that!. I will wait for the release version cause i have usage limits for my internet connection.
