      This error may be caused due to a *.def.lck file that is present in the folder: _filesdp0CFXCFX. Deleting the *.def.lck file will allow the CFX Solution cell to launch. The *.lck files are temporary lock files that CFX generates while files are in use. On rare occasions these files aren’t automatically removed and can interfere with the proper operation of CFX.
