Quartus ModelSim Memory allocation failure

Looks like the issue is with the WLF simulation file being in use by another user/program. This is the warning from ModelSim before it crashes trying to allocate more memory.

# ** Warning: (vsim-WLF-5000) WLF file currently in use: vsim.wlf

# File in use by: Richa Hostname: ECS-ZBOOK-17-G4 ProcessID: 50584

# Attempting to use alternate WLF file "./wlftykv95n".

# ** Warning: (vsim-WLF-5001) Could not open WLF file: vsim.wlf

# Using alternate file: ./wlftykv95n

I suggest you check if any other modelsim processes are in use via the Task Manager and kill it. Close all Quartus/ModelSim tools and kill all vsim/vlog processes that are running via Task Manager. Then re-open the project and try running the simulation.
