It is too late for this question but it might be helpful for someone else: I had the same issue but, after a while, i sorted it out.
Checking the error logs,

[MapExporter] Could not save [Path]/[textureSet]%09_BaseColor.png map: Couldn't open a device on file:///[Path]/[textureSet]%09_BaseColor.png

Checking why that non printable character (%09) was there, I found that the texture set names, had same extra "spaces" afterv the name. For some unkwon reason, ate a certain point in time (same proyect) 3DsMax material names where imported (.fbx 2020) whir those extra non printable characters as the texture set name. Just removing thoe scharecters from each texture set (one by one....) solve the issue.

Hope it will help someone.

Hey,
I checked the name and there was so many extra "spaces", so I fixed the name and no more errors,
Thanks for sharing ❤️

Same here, removing spaces fixed the issue, thank you all!

I just finished experiencing many of the same errors as this person above with many of the same MapExporter errors within the log. I don't know why it wouldn't work, maybe I had weird permissions set for the specific drive I was trying to export to? Anyways I was trying to export to my HDD drive. It being an HDD drive is probably irrelivant but I'll leave the detail in. Anyways, I changed my export location to another drive (which happened to be an SSD) and the export succeeded. I didn't have another HDD drive to test on, but I had another SSD drive and I attempted an export there and it was successful. So maybe drive/user permissions or some special characters in the file path... either way changing the output location solved my issues. Hope that this is helpful for someone else that has to deal with this silly odd issue. good luck!

Probably the directory where you trying to save the maps doesn't exist anymore ( if you use a project of another person on your PC the directory export of the project try to be on the directory of the PC that created the file )

In the Export texture setting change directory on a folder that yu like on your PC C:
