View.onUpdate() crashes on Edge 130 simulator

Hi, I have encountered a strange problem. All of my data fields suddenly crashes on the Edge 130 simulator. All other Edge devices run fine in the Sim, but with Edge 130 I get the following in the console:

Error: Invalid Value
Details: Failed invoking <symbol>
Stack:
- draw() at D:\grmn\prj\di\ciq\toolchain\mbsimulator\submodules\technology\monkeybrains\virtual-machine\api\WatchUi.mb:4254 0x30002a4b
- drawLayout() at D:\grmn\prj\di\ciq\toolchain\mbsimulator\submodules\technology\monkeybrains\virtual-machine\api\WatchUi.mb:1514 0x300023df

- onUpdate() at C:\Users\fredrik\git\DexDF\source\dexDFView.mc:195 0x1000166e

line 195 corresponds to:

View.onUpdate(dc);

My Data fields are complex data fields, using layouts. 

Using Eclipse IDE on Windows (v. 2018-12), Connect device simulator 4.0.1 and  Connect IQ SDK 4.0.2

AFAIK I have made no changes to the source code that could cause this issue. 

TIA
