Thanks for confirming and for the info about your version and distro. I can reproduce this on 3.2.11 on Ubuntu WSL.
The old related issue was closed without a fix, so I’ll open a new, narrower ticket specifically for this startup race around registering vscode-remote-resource:// in WSL, and I’ll attach your report plus a similar one from Extentions icons don't load under the extention tab on the sidebar. I’ll post an update here once I have one.
For now, as a workaround, either run Ctrl+Shift+P then Developer: Reload Window after restart, or use your --disable-features=OutOfBlinkCors flag.
