Owncloud issue: Your storage is full (windows 10)

Hello, I have a storage limit (22.7 Gb) in Owncloud account running on VM:
изображение_viber_2021-11-17_14-06-59-777

Increasing the storage in Virtual Media Manager does not help:
size

by the way, after the VM start the storage is not limited
22 of 30
however after some syncronization in Ownclowd client the error message appears.

How to fix this? Any helpful advices will be appreciated (unfortunately I did not find a solution in Google)
