gpu survey unsuccessful

LM Studio 0.3.15
under latest linux mint, everything is up to date
fails to detect my gpu (laptop rtx4060)
i deleted the .lmstudio folder because lmstudio was failing to detect my gpu after downloading and using the latest version and found in one of the issues from february that this could solve the problem
now i : lost all my models and chat that was working before (i was aware of this, but still went forward in hopes that i could actually use lmstudio)

error snippet when searching:

RPC handler: TypeError: fetch failed

Start by reproducing LM Studio 0.3.15 on latest Linux Mint with the laptop RTX 4060 and inspect the RPC handler failure shown in resources/app/.webpack/main/index.js. Compare GPU survey and search behavior before and after the .lmstudio reset; done means the GPU is detected without requiring deletion of user data and the reported RPC error is understood or resolved.
