PsychoPy Error: "Unable to create process..."

Hello.
I installed psychopy using conda in a new environment. It worked fine for a day or two, but then when I try running psychopy from the command prompt, I get the following error:

Unable to create process using:
“C:\Users\[name]\anaconda3\envs\[env name]\pythonw.exe”
“C:\Users\[name]\anaconda3\envs\[env name]\Scripts\psychopy.exe”

I have tried uninstalling and reinstalling psychopy and pythonw from the environment, but to no avail.
Please help!
Thanks.
