As the OP of this technical problem, this has worked for me, but ONLY if all of the settings have been turned ON or HIGH, the moment I switch back or de-grade them, game freezes. This is still a serious error in Apex, and it's quite shocking that no matter if this post / request is very hot and important, the support ticket is still open, and the hotfix (which is not much work to be honest - if some of us know and others suspect what the problem is). I won't close this topic, or accept this reply "as an answer" so the topic can stay hot and so devs can be alerted, and since it has worked for me but apparently not for everyone, the problem persists. I'll copy paste the solution that has (TEMPORARILY - RESPAWN THIS DOES NOT MEAN IT IS FIXED) worked for me so others can try this! Thanks to the owner of the possible solution for your time and help!
*Possible Fix*
As soon as you enter the game go into your video settings and use these options.
Sun Shadow Detail - > High
Sun Shadow Coverage - > High
Spot Shadow Detail - > High
Dynamic Spot Shadows - > Enabled.
Dynamic spot shadows being enabled seems to be the most important one*, change that first and see if the issues resolves.*
