make sure you have all 3 versions of the dot net framework installed. usually is the issue, highest one does not contain all, go to the FAQ section under "Endless loading / Stuck on splash screen / Game crash to desktop" this has the link to all three needed
I have this issue aswell and i can see it boot up but it instantly closes after like 1 second. I have all framework versions. SPT-AKI is fully up to date aswell as Tarkov. Also tried uninstalling all mods and changing the settings back too default value.
