Open button does nothing

[pmust]

Short description

Nothing happens when pressing the open button of a session, or through "open in new window" in the three dot menu. If I use "open in the current window", then only the first window opens (in a multi-window session) and all my other windows are closed. The "Add to current window" also only adds the very first window again but at least it does not close all my other windows.

If I check the debugger I get aa uncaught (in promise) Error: An unexpected error occurred error. Here's a pastebin of the message: https://pastebin.com/rAP4Cy6v. There is also a Security Error: Content at moz-extension://35a2790a-3032-4cd5-b4de-65642a85f2af/popup/index.html may not load or link to chrome://mozapps/skin/extensions/extension.svg. message that gets posted there but I am not sure if it is related.

I have tried to reinstall and downgrade but neither works. Also tried to disable all other addons but no help.

Steps to reproduce

1. Start Firefox with clean profile.
2. Install Tab Session Manager
3. Make a session.
4. Try to open it.

Actual result

Nothing happens but https://pastebin.com/rAP4Cy6v this is outputted to debugging.
