iPad wont show up in file explorer

I make art sometimes and I use both my PC and my iPad, so I need to sync them. I used to be able to sync my art from my iPad to my PC by plugging it in and pressing the iPad thing in file explorer, and I could do everything like normal. I wanted to move files from my PC to my iPad, and didnt see a way to do this (I've now realised you can email yourself...whoops) and I downloaded a program called Wondershare Tunesgo. This was a free trial because i didnt want to pay 60 pounds, and now the free trial is over i couldnt uninstall it. I had to manually find its' files because it had hidden itself and stuff, and now that I've removed it the iPad doesnt show up in file explorer anymore. My guess is the program changed the setting that allows that so I'd have to pay them to keep syncing, but i dont know how to enable that feature again. Can someone tell me how, please?

I've tried looking in device manager, and there wasn't a 'portable devices' option. I also looked under Universal Serial Bus Controllers and the Apple thing was there, so I know it's registered that my device exists. And I would install iTunes but last time I did this it corrupted my iPad, and the only way I could fix it was by wiping it completely.

I was definitely in device manager. everything that's usually there was there, but not portable devices. Ill try iTunes anyway though

Just tried, that did an entire nothing

it wont install. the setup thing downloaded, but after i install itunes itself and click finish, it goes away and it isnt there
