there's a couple of redditors with this issue too, doesn't seem very common at all though. pfb link to subreddit post:
My computer is nothing special, no graphics card and no solid state drive. It's pre-owned and relatively new but very basic. I run Java ok but with some lag. Bedrock i own but can't download due to this problem.
I have a similar problem to OP. I've tried all the fixes recommended on the reddit page above to date (it's currently 10 Nov '21). This is the first time i've tried to download a Bedrock that I already own if that makes sense. the difference between me and OP is that i haven't used bedrock on this computer before. i think i have it downloaded but not installed.Â
whaaaaa??? ok i'm such a noob omg thanks for coming back to me 🙂
