My bambu studio did not connect for the last three days so I wanted to use an open source client. But that crashed, too. Unless the bambu studio network plugin it gave out an UTF-8-coding error. Have a look at this filament description that was set to the external spool holder:

"vt_tray":{"id":"254","tag_uid":"0000000000000000","tray_id_name":"",
"tray_info_idx":"Pde2\xea58c",
"tray_type":"TPU","tray_sub_brands":"","tray_color":"FFFFFFFF","tray_weight":"0","tray_diameter":"0.00","tray_temp":"0","tray_time":"0","bed_temp_type":"0","bed_temp":"0","nozzle_temp_max":"250","nozzle_temp_min":"200","xcam_info":"000000000000000000000000","tray_uuid":"00000000000000000000000000000000","remain":0,"k":0.019999999552965164,"n":1,"cali_idx":0}

The solution after seeing this was simple: I went to the printer and assigned a generic pla filament to the external spool holder - and it's connecting again.

Interesting side fact: Even a factory reset before or coupling another account did not help. I don't know if the printer keeps the filament information in a non-volatile area or if it resynced it right after factore reset with data from the cloud after connecting my account....
