Earlier, while trying to install an application, got a "blue screen" error. After a PC restart couldn't start that application, was getting error 0xc000012f. Reinstalled all Vistual C++ packages, ran SFC scans, ran a Memory Scan and a DISM scan. Error 0xc000012f went away.
After all the, above mentioned, procedures I restarted my PC. Trying to start another application, previous app is now working, resulted in error 0xc0000005, uninstalled that app and downloaded a new .exe installer for that app. Same error (0xc0000005) with the installer, while all the other apps seem to run properly. Done a memory scan again, as before, 0 issues found. Done a SFC scan and reinstalled .Net and DirectX runtime. The same error persists (0xc0000005).
