There’s a megathread here showing people with low, mid and high end machines all experiencing crashes due to VRAM leak.
I haven’t done any of the things you said, and I have a relatively clean machine (purchased within the last 2 months).
When the hotfix came out a couple days back to fix this exact crash for 9th and 10th gen intel cpu users, it had the opposite effect for me hundreds of other people, and now our games are non-stop crashing due to a VRAM leak.
Do some research before playing pick me with the blizzard devs.
