Does this issue occur when all extensions are disabled?: Yes

Looks like the URI doesn't get the proper encoding...

[Xmader]

similar problem
If this file is in the recently opened files, even vscode can't be opened.

[jrieken]

Changes we make for 1.36 leading to too relaxed encoding, e.g now we skip over %<hex><hex> which isn't correct...

I just encountered this on mac and was completely unable to open vscode.
Deleting the following folder (which I believe contains the state of recently opened files for each project) made it possible to use vscode again:
~/Library/Application Support/Code

This folder includes global settings and keybindings keybindings.json and settings.json so remember to back these up!

Doing this also deletes the workspace states, including but not limited to: recently open projects, recently opened files, unsaved files, open tabs, tab configurations etc.

Here is the stack trace:

This prevent code on Ubuntu to start if a faulty uri is detected

[isidorn]

I have verified that I can create, open and edit a file %a0.txt. Thus adding verified label.

[hinzhelg]

Had to delete "/Users/{USERNAME}/Library/Application Support/Code/storage.json". Now it starts again and is working fine.

Thanks for the thread.

On mac's remove this file: ~/Library/Application\ Support/Code/storage.json

[jrieken]

Less intrusive workaround (will preserve your file history):

• rename storage.json to storage.json.old
• restart
• wait till we release 1.36.1 later today
• rename storage.json.old bad to storage.json

Generally, the issue is that we 1.36 struggles to parse file paths that have %<hex><hex> in it, e.g. %a0.txt or fome%ef.foo and despite starting with a fresh storage.json this will come back as soon as such a file is being opened.
