Describe the bug

I When using Fish shell, CTRL+SHIFT+U and CTRL+SHIFT+J do not work correctly. To reproduce: simply install Fish Shell

apt install fish

and select it as main shell

chsh -s $(which fish)

Then in VSCode run CTRL+SHIFT+U or CTRL+SHIFT+J

Result - I get a terminal with this text in it:

PID_FILE_NAME=1739206858557  node "/root/.vscode-server/extensions/jellydn.fzf-picker-0.9.2/out/commands.js" "findWithinFiles" "/root/ConceptReader"

also, if I press escape I get this:

~/ConceptReader main ❱ 
 PID_FILE_NAME=1739206859829  node "/root/.vscode-server/extensions/jellydn.fzf-picker-0.9.2/out/commands.js" "findWithinFiles" "/root/ConceptReader"
