Something wrong with dfx version 0.26.0

I upgrade my dfx from 0.24.0 to 0.26.0, then i keep getting error said CanisterIdNotFound

Also, when run ‘dfx start --clean --background’, it looks like not actually running at background, i can’t keep typing any other command, need open another tab to type command

But ‘dfx identity list’ works fine

To be clear, this is not --background failing to apply, this is dfx start failing to run. Can you try running dfx killall?

Can you post the output you see if you add the -vv flag to that start command?

For additions, I use dfxvm to switch to 0.25.1, it was working:

@Frankessa @heyuanxun are you starting dfx from a directory that has a dfx.json file with a network definition? If yes, can I see what you dfx.json looks like?

That doesn’t look like it should be a problem.
Can you confirm what you’re running this on (macos / windows wsl… and any applicable version numbers)?
Can I see the output of these commands - please run them outside of your project folder:

# to see the networks file you are using if any
dfx info networks-json-path

# to see the contents of the file
cat "$(dfx info networks-json-path)"

# stop dfx just in case
dfx stop

# start dfx
dfx start -vvvv --clean

# From another terminal
dfx ping

I have tried on macos and ubuntu, I found that the latest version can work smoothly on ubuntu, but on macos, not only this type of error, but also with high cpu useage problems.
