Constant/Consistent Game Crashing in All Modes - Even Fully Vanilla

OS: Windows 10 64-bit
CPU: Intel(R) Core i5-7200U CPU @ 2.50GHz (4 CPUs), ~2.7GHz
RAM: 6144 MB (6 GB)
Graphics: Intel(R) HD Graphics 620 w/ Approx. Total Memory: 3134 MB

Since roughly two months ago, I've been experiencing constant and consistent crashes. Crashing occurs in all modes: live, build/buy, cas, gallery, manage worlds, loading screens, and main menu. Most of these crashes would classify as game crashes that produce lastCrash.txt documents, but once I started troubleshooting, it would cause Blue Screens of Death (memory_management, bad_object_header, and page_default_in_nonpaged_area).

I've done countless measures to fix this issue:

1. Graphics Driver Updates & Fixes
   - Used Intel Driver & Support Assistant (found no updates)
   - Manually downloaded and installed latest Intel HD Graphics 620 driver
   - Used DDU (Display Driver Uninstaller) in Safe Mode to fully remove old drivers
   - Reinstalled Intel HD Graphics 620 driver from Intel's official site
    - Checked Device Manager and confirmed driver installation (initially reverted to Microsoft Basic Display Adapter)
2. Graphics & Game Fixes
   - Switched between DirectX 11 (-dx11) and DirectX 9 (-dx9) via EA App launch options
   - Deleted Options.ini to reset Sims 4 graphics settings
   - Lowered in-game graphics settings to minimum
   - Tested game in windowed and fullscreen mode
   - Repaired The Sims 4 via EA App
   - Fully uninstalled and reinstalled the Sims 4 and manually deleted Documents\Electronic Arts\The Sims 4 folder to let the game rebuild it during the next game load
   
   
3. System Stability Checks & Fixes
   - Ran mdsched.exe - no RAM errors found
   - Increase virtual memory (pagefile size) to prevent out-of-memory crashes
   - Reset virtual memory settings back to default
   - Ran SFC /SCANNOW and DISM commands to check for system corruption
   - Checked Task Manager performance tab for CPU/RAM/GPU usage
   - Monitored internal temperatures using CPUID HWMonitor
   - Set Windows Power Plan to High Performance to prevent throttling
   
   
4. Testing Without Mods & Custom Content
   - Removed Mods folder completely to test a vanilla game
   - Deleted localthumbcache.package to clear cached mod data
   - Game still crashed in vanilla mode, even with lowest settings.

In my 11 years of playing the Sims 4, I've *never* experienced crashing like this. I'm at a complete loss of what to do or where to turn next, and I don't have the funds to physically upgrade my hardware/equipment. I've attached the lastCrash.txt file as a Google Drive link (the attachment feature on here isn't working).

Any help whatsoever would be beyond appreciated!!
