That error is apparently coming from this line of code in the asar package's lib/filesystem.js:
this.offset = BigInt(0)
And, the error apparently means that you have a version of nodejs that electron is using when it builds your app that does not support BigInt which was added in v10.4.
So, though you think you are using v14.15.1, that is apparently not what electron is building your app with. You need to upgrade the version of nodejs you're using in this electron project.
You can confirm what version of nodejs is being used by adding this to some of your own code in the project:
console.log(process.version);

"'BigInt' is not defined" for build-in BigInt · Issue #11524 · eslint/eslint
January 24, 2019 - Please include the actual source code causing the issue, as well as the command that you used to run ESLint. let totalPrice = BigInt(0) totalPrice += BigInt(123) f (BigInt(totalPrice) === BigInt(0)) console.log('PAID') ... What did you expect to happen? BigInt should be recognized as build-in object and there should not be "no-undef" error.

ESLint — How to Fix “BigInt is not defined” - Future Studio
September 10, 2020 - Activating the es2020: true setting in your ESLint’s env configuration tells the parser to recognize ES2020 globals. And recognizing ES2020 globals includes the BigInt class.

If you manage your node version using nvm, please check if node -v and nvm alias default returns the same node version.
Tools like jenkins, forever... which start nodejs application, will use the default version of node, which could be different than the version used by terminal console.
Do the check: nvm list
Fix the difference: nvm alias default "node -v"

In fact, I already find the cause in the commit history. This issue is caused by this PR #13213 with this commit acfea9d by @sokra . In this commit, it's using BigInt which brings this issue.

BigInts are returned as-is. ... Strings are converted by parsing them as if they contain an integer literal. Any parsing failure results in a SyntaxError. The syntax is a subset of string numeric literals, where decimal points or exponent indicators are not allowed.

"BigInt is not defined" in React - javascript
July 8, 2021 - I am trying to use a BigInt value in React, and it is returning an error that BigInt is not defined. We are using node version 14.14.0, and BigInt is supposed to be supported as of 10.4. It's not a browser issue because 1) the latest firefox supports BigInt and 2) the app is failing to compile, so the browser isn't loading the page.

November 21, 2023 - Note that Javascript numbers larger than 9007199254740992 and smaller than -9007199254740992 are not precisely represented numbers and will not produce exact results. If you are dealing with numbers outside that range, it is better to pass in strings. Note that bigInt operations return bigInts, which allows you to chain methods, for example:
