Validating Profiles blocks users from accessing other profiles until the validation is done

[JillieBeanSim]

Describe the bug

Validating Profiles blocks users from accessing other profiles until the validation is done, which can sometimes take 30 secs or more. The user is not able to add another profile or run a query on another tree element while a validation is running.

To Reproduce

Steps to reproduce the behavior:

1. Run a search query on a profile that may take some time to validate
2. While waiting on the validation try to run a query on another profile
3. Must wait on original validation to finish before next search query can run

Expected behavior

Should be able to run multiple queries asynchronously and not have to wait on validation of a profile.
