JSON metadata file is not valid. Please check configuration of your server.

I have many mbtiles works fine. but only this one cause php server-crash.

I know it is index.json wrong, mayb double quote somewhere.

But how to fix this index.json issue?

Can't attache file here because it is 5GB too large.

I found solution:

problem tpk is generated from this workflow, which is not working:

step 1: create tile cache by
ArcPro > view > arcToolbox > data management tool > Tile cache > management tile cache
this create a tile cache folder

step 2: export tile cache foler to tpk file.
ArcPro > view > arcToolbox > data management tool > Tile cache > export tile cache
choose tpk format

solution: instead of problem workflow, you should directly generate tpk by
ArcPro > view > arcToolbox > data management tool > package > create map tile package

directly generated tpk file works fine.

DO not close yet, I still don't know how to fix problem mbtiles? Even I have work around.
