It could be WTT Head and Voice Selector.
This seems very similar to an issue I had recently. The fix is to set your character's voice in Tarkov's actual settings page instead of Head and Voice Selector's menu. That fixed my inability to go into the Hideout and go into raids.
You are probably right, I will install all my mods again on my new install and if it happens again, ill do that and come back to say if it worked or not. In case anyone else has this issue.
Thank you tons!
