Psychopy works much slower than before

OS: Win10
PsychoPy version: 2020.2.5
Standard Standalone? (y/n):y
What are you trying to achieve?:
Hi everyone;

I was designing a cognitive task(about attention) with Psychopy.So far, the program has worked well and the task has been implemented , but after I did not use Psychopy for a few days, I had a problem.
Now, whenever I want to run a task, I have to wait for about ten minutes for the task to run and Psychopy works much slower than before even for a simple stroop task.
What did you try to make it work?:
I reinstalled Psychopy but there was no change in the performance of the program and now program runs very slowly.
What specifically went wrong when you tried that?:
I have the same problem and the program works very slowly and the task runs much slower than before; also no error message is displayed.

How can I resolve this?
Thank you,
