Ok, I was just checking to make sure you had at least a good save point.
Sounds like it might be a permissions thing on your GTA 5 + RPH itself. You can right click on GTAV folder (since you have Epic) and go to properties and I think it is Security and add permissions for your user. Also consider adding the same to the lspdfr folder inside your GTAV folder as well.
Also consider whitelisting the GTAV folder with your AV and Firewall to make sure, but it looks like you are getting fairly far into the load screen having LSDPFR crash on you. Last but not least, make sure that your RageNativeUI is updated (most plugins have outdated ones these days) if you have other plugins installed.
