There is nothing in Process Lasso that would, or really could, cause a game to crash like that.
If there is a correlation, it has to be related to the power plan.
The 'Performance Mode' of Process Lasso induces the 'Bitsum Highest Peformance' power plan. You can change it to not enter that power plan in 'Options / Performance Mode Settings'.
Be aware of the power plan you are in and try staying in 'Balanced'. I bet it doesn't happen then.
From your symptoms, it may the GPU overheating, so you may also want to watch temps.
