I somehow failed to crop out my Steam username twice in a row, sigh, reposting again. KSP will not start through Steam, launcher indefinitely loads and gives this error. Modded install but nothing has changed since the last time I played when it worked. Validating files, uninstalling/reinstalling KSP, and restarting laptop have all failed to fix it. KSP_x64.exe still works but Steam launcher seems completely borked.

Completely uninstalling all mods and creating a new KSP Steam install from scratch still didn't fix it. The game is as it would be out-of-the-box vanilla and the launcher is still broken in Steam.

#

Deleting launcher data didn't work either.
