Have "Error using tlc_new" when trying to build Simulink model

Hi,

I was trying to build my Simulink model. The model runs OK. But when it builds, it gives error like below. Does somebody know why this happens? It looks like to me that it's error from an automatically generated file which I have no clue how to solve it.

Hi Jason! I'm having same issue. Did you finally figure out what the issue was and how to address it ?

Answer 1

[Ben Triplett]

I had a similar issue. I deleted ALL folders containing any build artifacts, all temporary files such as .slxc etc. Rebooted and the error went away. My particular error message was: Error using tlc_c This object cannot be serialized

[Jonas]

This worked for me as well, closing all and restarting MATLAB.

[Andy]

I had to go a step farther and reboot the PC. Several of the files "temporary" files were still held by some other program, even an hour after Matlab had been closed. Things seem to be back to normal now, although I still don't know what I did different in the first place.
