Show a connection error when load agda file

[m4p1e]

The error showed in the vscode console as follows.

Connection Error: Internal Parse Error
Perhaps the underlying protocol used by Agda for communicating with agda-mode has changed.
Please report which version of Agda you are using.
Error code: R0 ""Warning:""

When I use emacs, it works as good. My agda version is 2.6.3. I have checked the agda path in extension setting, and it points right path.

This connection error was solved after updating vscode. But it is stuck at "loading..." and does not advance. I tried to load different agda files and both of them got stuck.

Vscode: 1.99.3
Agda-mode-vscode: 0.5.6

Any agda files. It looks like that

I have verified that the agda process started, such that

ps aux | grep agda
maple     224595  0.0  0.0   2620   600 ?        S    21:08   0:00 /bin/sh -c "/home/maple/.cabal/bin/agda" --interaction
maple     224596 22.5  0.7 1074112344 231696 ?   Sl   21:08   0:02 /home/maple/.cabal/bin/agda --interaction

It always show Loading. I have updated the extension to 0.5.7, but same. Need I provide some logs or something else?
