SKR-V2 + TMC2209 suddenly doubles the flow #96

Hello! My 3D printer configuration: SKR-V2 (BigTreeTech) + TMC2209 (BigTreeTech) working on UART. In Marlin config file TMC2209 drivers set up. I encountered a problem sometime ago. After the 3D printer was fully equiped I was able to print one full item. But then, after I've started to print another one this happened: image image After a nice beginning part if somehow nearly doubles flow of plastic. Right in the middle of printing process. That's strange, and I found one issue in main branch of Marlin: https://github.com/MarlinFirmware/Marlin/issues/22996. Maybe it is connected. Can you help me, how this can be tested. Because answer of M122 command seems normal. Only also strange thing I could notice, was that UART Enabled field is False False False False. Is it correct? Thank you!

A strange problem. Try to provide more information. Configuration files Marlin. Output to command M122 before error and after error. Photo of TMC 2209 from below. Photo of pin connection on SKR 2 under TMC 2209. ...
