Pytesseract image_to_string no longer working?

Question

The program so far reads in images uses opencv, modifies them so the text can be read more accurately and I'm at a part where I want to add each image's text (string) to a list. This is where something's not quite right.

I was able to use the image_to_string successfully in a previous script however now that script isn't working either. I'm on my work laptop using PyCharm in a conda environment. Here's my code, it's the very last for loop where the problem is occuring:

EDIT: I've tried running another script which uses image_to_string which had previously worked however now it doesn't. This confirms that the code isn't wrong, it must be how I'm set up with PyCharm and Anaconda. The conda environment is active and I have correctly linked the tesseract.exe I believe and I'm not sure what else to try

找到了解决方案......我很傻 - 我需要做的就是通过 Anaconda 启动 PyCharm，而不是运行它
