FLINT 2 - LuCi-app-SQM - error 255

Hey, I'm new here and totally new to OpenWrt. I ran into a problem while trying to reinstall luci-app-sqm. After installing the QoS and sqm apps, I decided to remove them and install only one, but now I'm having trouble reinstalling it. I'll share some screenshots of the error I'm getting. can someone help me ?

Since you're using the GL-Inet firmware, you need to ask on their support channels.

Alternatively, you can install official OpenWrt:
