This problem has been around since the 20.03 version came out in April, 2020. I'm afraid it's going to take a while for them to upload another version. So, what I recommend is for you to reinstall the older version you used to work with (if you deleted it like I did). Hopefully, you will have Code::Blocks working as well as it used to soon. Here's a link to the oldest versions: www.codeblocks.org/downloads/5. Good luck!
