This happens if there is an entry with dummy repository in user's inbox/recentViewed.

Version-Release number of selected component (if applicable):
6.2.2

How reproducible:

Steps to Reproduce:
1. In 6.2.0 business-central, clone attached repository (repository620.zip)
2. in Project Explorer, open project1 in cloned repository and open assets
and confirm no error happens.

testProcess (Business Process)
testGDT (Guided Decision Table)
testGRL (Guided Rule)
isAdultTest (Test Scenario)

3. perform Build&Deploy and then start business process named 'testProcess'
then confirm process status by Process Model via
Process Management>Process Instances>Open a process instance>Options>Process Model

4. back to Project Explorer and see above 4 assets can be opened correctly
5. stop BPMS620, apply patch 6.2.2 and then restart it
6. login business central as a same user and open above assets again

Actual results:
unable to open process designer
error 'No such file...' is shown and these assets are no longer edited.

Expected results:
open and edit these asset without any problem

Additional info:
This issue is relevant to BZ#1317671.
If you login business central as the other user, you can manage these problematic assets without this issue.
