Maybe the log contains some information about the error?

A pointer stored in FSR1 overwrites the RAM. Simulation stops when PCLATH is overwritten.
When the simulation stops, PCL is 0xBD, so the error caused when PCL is 0xBC. PC can be 0x00BC, 0x01BC or 0x02BC.
Disassembly listing will help you to find the error in your code.

There is a goto 0x1BD on address 0x1DF. Before this, there is a movwf INDF1.
At this point, there may be a wrong address in FSR1.

Without disassembly listing hard to find more information.

@cpexpert6 are you sure you compiled for the correct target?

As @nemka mentioned there is a movwf INDF1.
At that point FSR1 contains 10, which writes content of W to PCLATH (address 10).
That causes the jump out of the Program Memory:
eMcu::stepCpu: Erro PC = 4541 Tamanho do PGM = 2048

This was generated by the compiler, which is not very likely to make this mistake unless it thinks it is some other device.
