Also for me ; Cannot read properties of null (reading 'signTx')

Struggling with mynode.
it was built in the first days of the tesnet, now i have upgraded everything but is impossible to add my node on the network.
i use flintwallet extension on windows 11

It.s also impossible to delete the previous node or build a new one on the same device even if i disinstall the app.
Everytime i try to setup a new one the old one is there.
