Unable to share folder as jpeg or heic, but Artstudio format works normally.

[Jerelo]

I was trying to make jpeg backups of my art, and I found that it was taking too long. Using a smaller folder with 4 artstudio files, I confirmed that I could export the folder. It took a few seconds. When I then chose the jpeg fomat, the export went on without end, until I cancelled after 15 minutes. The same thing (interminable process) happened when I chose the heic format. I am working with current IOS and artstudio 4.1 on an iPad Pro 13" gen 3.

Anyone else see this bug? Is there a workaround? Are the developers aware of this?

Please write all steps to reproduce the issue. Or just send a screen video.

My steps:
1) select a folder and long press to reveal share.
2) select export and choose jpeg as the export type
3) program displays cycling clock, but never succeeds.

Selected folder was on iCloud, in documents.
As mentioned, exporting in artstudio format is successful using the same source folder.
