We are running on Sitefinity 5.4.4040. We have a dynamic content and I attempted to add a field to the existing module using the module builder. I create the field successfully, but when I click Finish I get an error. I checked the log files and discovered the following:
Event message: An unhandled exception has occurred.
Exception type: LockRecursionException
Exception message: Write lock may not be acquired with read lock held. This pattern is prone to deadlocks. Please ensure that read locks are released before taking a write lock. If an upgrade is necessary, use an upgrade lock in place of the read lock.
Has anyone ever experienced this before? Any help would be appreciated. Thanks!
Yes, I added 3 fields in total just for testing purposes and the same issue happened. I tried another module and the same thing happened, so I do know it is not tied to this specific module. I do not recall that this same thing happened for newly created modules. I believe it only happens for modules already created.
