If you choose UoPeople to WGU, here's how it'd go.
UoPeople requires a high school diploma equivalent and English proficiency. If you meet that, you're golden.
The school uses a process they called "foundations" in which you take basic college-level courses to demonstrate the ability to complete them. If you maintain a decent GPA in those courses, you are granted "degree seeking status." So, essentially, you meet the minimum requirements and then earn your way into the program.
You will not need to submit your previous transcripts when you apply. However, I would recommend submitting them later and transferring any credits your can. No sense in repeating what you've already studied.
Even if you do submit your transcripts when you apply, I seriously doubt it would hurt your chances. The school is very big on "access to higher education," so denying you would run counter to that.
You could also try reapplying to WGU. If you struggled in community college, WGU might not work for you--yet. Then again, UoPeople might not either. If you feel like you've grown since then, developed better study and time management skills, then give either a shot.
Another option is that some universities offer "academic forgiveness."[0] It's basically a way to help students recover from a rough start.
