I'm also facing this issue when using the desktop client for Hoppscotch. When I import collections exported from Postman into Hoppscotch, the import message says the process was successful. The collections appear in the Hoppscotch workspace, and I can momentarily see the requests along with the custom variables used in them. However, after refreshing the desktop application, they disappear. This issue is observed whether or not the collections include post-response scripts. I tried using the Docker-hosted version of Hoppscotch, and this issue is not observed there. Based on my experience, this problem appears to be specific to the desktop client application. I have not tried the web version.
