PENDING Unable to use task sequences multiple times on the same computer, no task sequence available error

[Corta]

Hello everyone,

For some time now, for an unknown reason, I have been unable to use task sequences multiple times on the same computer.
If I take a completely new computer, use my WinPE boot key, I can see my list of task sequences (4-5), I select one, execute it, and it runs correctly.
However, if I now want to use this same computer to execute another one of these task sequences, I get an error 'No task sequence available for this computer.'

I noticed that if I take a computer which is running for a few times, I have access to TS but MECM is creating duplicate computer entries :


My temporary solution is to delete the most recently created computer entry via the MECM console. After doing this, I can execute a task sequence again.
However, I would like to understand why this is happening.

After some testing, I found that I can 'approve' the machine instead of deleting it, which allows me to retrieve my list of task sequences. However, I still don't understand where this state is coming from
