[DamianoPantaniHT]

Exact URL of where the bug happened

https://lichess.org/analysis#explorer https://lichess.org/{anyGameId}/black

Steps to reproduce the bug

• Open any analysis board (game analysis, openings explorer)
• Click the target icon, Stockfish will evaluate position and calculate best moves
• Scroll a few moves
• App gets stuck at "Calculating moves" / "Computer thinking". Easier to reproduce with unusual moves, or e.g. dynamic sacrifices aka blunders

What did you expect to happen?

It doesn't get stuck

What happened instead?

It gets stuck every time, first 10-ish moves are usually OK though!

I'm also having the same issue on MacOS Monterey version 12.1, Google Chrome Version 112.0.5615.137.

I have this issue for most games when I go to the analysis board, turn on the engine, and jump to a random move in the middle of the game. A refresh almost always fixes it, but this becomes annoying when I'm solving puzzles (I have the same issue there as well). It will eventually load the evaluation, but only after a couple minutes or so.

Here's a screenshot of the console output, doesn't seem to be anything there

I was testing Lichess on my desktop browser, Brave, but for mobile resolutions: 400px. It worked just fine. Then I switched to the mobile emulator in Brave. Same resolution, only now when I start the engine I often get "SF: Failed to allocate 1024MB for transposition table" and then nothing will fix it except a refresh. I set the memory to minimum, to no avail. If it gets to this state it never recovers. But it ONLY happens in the emulator. (set to Responsive 400px). Perhaps this can give you a clue about the people complaining about the engine getting stuck on mobile.

The same bug, browser tab getting stuck while loading stockfish engine. Several months ago it worked fine, but now It doesn’t. It happens on IPad, Firefox, Chrome.
