Hex.Application error trying to run mix deps.get

I tried to run mix deps.get and get this error:

Since I only upgraded to local.hex 2.5.0 last week I tried downgrading. SImilar problem. Found that there is a 2.5.1 which sounds like an emergency upissue so tried that. Same prblem. ANy idea what’s going on? I don’t expect this is me, but tell me if there is a workaround?

p.s. I don’t seem to be able to insert a code block with triple ticks. As soon as I type the third one this window hangs. Tried it about three times in different ways before abandoning hope.
