I have similar issue.

Microsoft PowerToys version: 0.84.0
Installation method: PowerToys auto-update
Running as admin: Yes
Area(s) with issue?: Workspaces

Steps to reproduce: 
Setup Workflow.
Instance 1 commandline arguments "https://example.com/1".
Instance 2 commandline arguments "https://example.com/2".
Instance 3 commandline arguments "https://example.com/3".

✔️ Expected Behavior:
Instance 1 open https://example.com/1.
Instance 2 open https://example.com/2.
Instance 3 open https://example.com/3.

❌ Actual Behavior: 
Instance 1 open https://example.com/1, https://example.com/2, https://example.com/3

Currently, the workaround is to open each URL in a different browser.
