[Instruments freeze but aircraft is still airborn]

I don't know what type of bug or error is this but its similar to a wasm crash, I had face this issue many times before, I tried adjusting the graphic settings  hoping to not have this issue again, and here is the result of my screenshot and what else can I do to prevent having this bug again?

 

  just my luck  

[ineed of assistance for further steps for costume livery]

Im currently working on a costume livery for the A350-900, after reading the steps on the manual, I worked on the fuselage, broken into 4 main parts on PS, convert them into DDS files for the 2020v, Im aware 2024 requres XMLs in order to work,  and the main question is where in the aircraft texture in the community folder can I place the 4 main A359_Fuse_ALBD(fuselage) also the winglets, and tail texture files  in order to work.  

I was exploring each aircraft file of inibulds a350 in the community folder and theirs so multiple texture folders and non of them have the 4 fuse parts and i'm very puzzled about where can I place my costume texture files

[see through in the cargo hold and windows on a350]

since the SU3, the inside the cargo hold and the lack of the passenger cabin means you can see straight through it on external view and I dont know if anyone is having this same issue
