What is MEC?
Thee are several basic approaches for this problem in this tread, did you made sure nothing is applying to you?

MEC = Mirror's Edge Catalyst, & I don't know how to check to see if my drive is formatted in exFAT.

Right click "Start" > Disk Management. > look under "file system"
You run frosty as an Administrator?
June 2021
1. Yes, I've been running Frosty as an administrater.
2. Both of my drives are listed as "NTFS"

Then I would recommand to contact the Frosty team itself.
Here is the Homepage, there are links to know issues and the Discord community server at the bottom of the page.

How do you know which type the drive is?

You can fix it by moving the game in any NTFS drive folder,either that or obviously the not so optional format,I also have this issue but mine is a unrepairable one cause my game mods and mod manager are all in my C drive which is NTFS formated and this issue still appears,it worked yesterday just fine but today this popped out.

delete mod data from the game golder also delete the cache from mod manager and delete frosty from %localappdata% and then try to add the mods again,if the issue persists then maybe a datapathfix should be added.
