Microsoft Edge for the “Read aloud”

Microsoft Edge for the “Read aloud” when viewing PDFS. For some reason, it’s not working now. It won’t let me select individual chapters to use the “Read Aloud” function on it. It always goes to the first page to start to read it instead of what I want it to read. Also, it won’t highlight or move the page down as it reads, it’s like it’s frozen but yet it’s not at the same time. There is some glitch happening here. I tried resetting it, cleaning the cache, highlighting a word for it to read, right-clicking, and selecting “Read Aloud” that way, but nothing seemed to work. Could something be blocking it from going to individual chapters? Is there another way to fix this? Will there be a new update with fixes? Should I delete Microsoft Edge and try to reinstall it??? Please, help.
