As @mostlydrinkstea says, this is the age old theodicy question and has been batted round a million times. As a Christian I don't pretend to find it easy, I join with many of the psalmists in scripture when they ask where God is, and then also join with them in their active decisions to remember and to trust, and find a peace beyond anything I can comprehend in doing so.
I do find the free will argument helpful, because what some are saying is in essence this: you have a child who commits a crime; therefore you caused that crime. Can this be said to be true? Possibly, in terms of how you shaped the child, but all children have their own free will to do whatever they want to do, whatever you have inputted as such.
For me, the question at present isn't about whether God caused it - as the cause of everything one could argue indirect cause - but how God responds to it and how we respond to it. As one of the 'shielded' group who got a text yesterday saying I am at serious risk I am starkly aware of the horror and reality of this and what it could mean, and my own stress and panic about it as someone with severe respiratory disease. However, having suffered pain all my life, I've come to know a God who enters into that with me because this God does not stand separate and aloof, but demonstrated this great and ultimate love in Christ's life, death and resurrection. I live in the knowledge that Jesus did not shy away from pain and suffering but took it all, every single thing, upon his body and soul on the cross, and so knows what we suffer. Instead of a God on some distant cloud-throne we have a God in the mess with us, weeping with us, weeping at the mess we've brought upon ourselves and at the pain it causes, the pain we go through.
For me, the hope I've found amidst my own pain has meant that I can take hold of something even greater than the questions that I still ask, and it's a hope that sparks joy in me even in darkness, that brings life to me even when I hurt. It's a hope which means even now, so starkly aware of my own mortality, I can say that I wait with anticipation for what will come if I do die, with longing and with a sense of knowing the pain will be done and who I am will be utterly freed and utterly fulfilled. That does not mean I eagerly embrace the possibility of death - far from it. I do not want to leave my family. I am scared of that. I am scared because I have a sore throat and chest pain today. But hope still sustains through my fear and carries me forward through my isolation.
