Premiere v.25 6.3 Mac | Selection tool defaults to add vertex tool when masking

Hello! I'm wondering if anyone else is experiencing this issue: I've been trying to create a simple mask and edit it's path but premiere is not allowing me to drag points with the selection tool–even though it appears as if it is selected in the tool bar. Instead, it turns into the "add vertex" tool which makes it almost impossible and tedious to make a clean, easy mask path. I don't know if this is related to the newest update, but when I first started experiencing this issue this morning, I cleaned my cache, restarted the app, updated my computer's software, and then when I tried to click back into my project file I was told that the software was corrupted and needed to be deleted. I uninstalled it–which of course fixed nothing. Then, I ran the adobe cleaner tool which finally allowed me to run Premiere again. I was hopeful that would solve this masking issue, but nope!

I'm wondering what else I can do at this point. Premiere's bugs have been slowing down my workflow tremendously, so if anyone has any experience with this or any tips please let me know!
